    TECHNICAL AREA
    This presentation concerns the doubling of structures in general, and in particular but not limited to, the doubling of frames.
    The present disclosure relates in particular to a bracing device which can be used for fixing a lining framework to a structure to be doubled.
    The bracing device according to the invention is particularly suitable for the lining of old frames, and for the lining of so-called “monopan” roofs.
    BACKGROUND OF THE INVENTION
    In known manner, the lining of a structure uses a covering system which usually comprises a lining of thermal and / or acoustic insulation such as mineral wool, most often a membrane, for example a barrier membrane. steam, which is applied against the insulation lining, and facing panels such as plasterboard or false ceiling plates which constitute the lining facing. To fix the facing plates, a metal frame made of profiles is attached at a distance from the structure to be doubled, the insulation lining being interposed between the structure to be doubled and the profiles.
    In order to facilitate the installation of the insulation lining and the fixing of the profiles, it is known to use bracing devices which serve both to bring the profiles at a distance, and to keep the lining in place. insulation and membrane.
    Patent application WO 2009/103911, filed by the applicant, describes a bracing device of this type comprising a rod provided at its rear end with a fixing plate pierced with holes adapted to receive screws for fixing to the structure to be doubled, and, at its front end, with a tip for skewering the membrane, around which is attached a removable cover head, sandwiching the membrane at the periphery of its skewer opening, the head being further dedicated to assembling the rod with a profile.
    This type of device is not well suited to certain sites on which the height between the structure to be doubled and the doubling is not the same over the entire extent to be doubled.
    This is the case for example of the old frames: over the years, the wood which constitutes the rafters of these frames has worked, that is to say that it has deformed. The rafters, on which the bracing devices must be fixed for the lining, are therefore often twisted or bent.
    This is also the case for some contemporary houses, with so-called “monopan” roofs: these roofs can have a difference in height between the top and bottom of the slope up to 20 cm.
    In this type of case, the operator must provide several references of the bracing device, of suitable lengths, to carry out the doubling. It is necessary for him to carry out preliminary calculations in order to assess the number of lines of each length to be provided, or to take on site a surplus of material, which can prove to be costly and cumbersome.
    OBJECT AND SUMMARY OF THE INVENTION
    One of the objectives of the present invention is to provide a system which makes it possible to remedy the aforementioned drawbacks.
    This objective is achieved with a bracing device for fixing a lining frame on a structure to be doubled, in particular on a frame, said device comprising
    a main body comprising • a rod, in particular adapted to receive a membrane plugged in on it, extending in a so-called axial direction, and • a base for fixing to the structure to be doubled, at a rear end of the rod, and a connecting piece provided with means for fixing to the lining framework, adapted to be assembled at a front end of the rod, the bracing device being characterized in that it comprises a step adjustment mechanism of the length of the body by relative sliding of the fixing base and the rod, said adjustment mechanism being configured so that the fixing base and the rod are adapted to slide relative to each other in the axial direction in a first relative angular position, and the fixing base and the rod are only adapted to pivot towards a second relative angular position in which they are locked in axial translation than in a plurality of adjustment positions staggered in the axial direction in a coarse pitch P of between 0.5 and 5 cm, preferably between 0.5 and 2 cm, even more preferably between 0.8 and 1.3 cm.
    The bracing device according to the invention is a device adjustable in length. Thanks to the body length adjustment mechanism, the operator can use the same bracing device for different dubbing heights.
    Furthermore, the adjustment mechanism being staggered in a coarse step, the adjustment is done quickly. The operator can only choose between the different adjustment positions, regularly spaced. A simple calculation allows him to adjust the device to the desired length.
    The membrane is advantageously an air tightness and / or water vapor management membrane, preferably a membrane ensuring both these functions. The water vapor management membrane is advantageously a vapor barrier membrane or a humidity-regulating membrane, that is to say one whose vapor permeance
    of water varies depending of relative humidity ambient. We hear by the term "skewered" than the rod crosses the plane of the membrane, with or without piercing
    prior to said membrane. The membrane can therefore be pierced prior to skewering, the rod then passing through the opening produced by this prior drilling. Alternatively, the membrane may not be pierced prior to skewering, the opening then being produced by the rod itself at the time of skewering. In all cases, the opening through which the rod passes will be called in the remainder of the text "opening of skewering", whether it is created by skewering or prior to the latter.
    According to one example, the bracing device further comprises means for locking in rotation the fixing base and the rod, in the second angular position.
    According to one example, the locking means comprise clipping means.
    According to one example, the fixing base comprises an adjustment part adapted to receive the rod and provided with a plurality of notches spaced axially from the coarse pitch P, and the rod comprises lugs formed at its periphery and adapted to cooperate with said notches .
    According to one example, the clipping means comprise a clipping tab delimiting a notch of the adjustment part called the locking notch, adapted to move by cooperating with a lug of the rod during a rotation from the first to the second position angular and to prevent the return of the lug, once the second angular position is reached.
    Preferably, the device comprises means allowing the return to the first angular position under the effect of a relative rotational movement of the rod and of the fixing base, or of the combined effect of a translation and relative rotation of the rod and the fixing base.
    According to an example, the rod has at least one axial groove and the adjustment part has at least one internal allowance located near its front end, and adapted to slide in said groove when the rod and the adjustment part are in the first angular position. These arrangements allow the operator to easily identify the first angular position, in the laguelle the length of the body can be adjusted by relative sliding of the rod and of the fixing base.
    According to an advantageous example, the rod also has a plurality of circumferential grooves extending from the axial groove and parallel to each other, the internal excess thickness of the adjustment part being adapted to penetrate one of said circumferential grooves during the passage of the first to the second angular position. These provisions allow the operator
    6 to access more easily to positions of setting device. According to a example, the stem present a section superior of security lacking of grooves
    circumferential. Thanks to these provisions, the operator is prevented from carrying out an assembly in which the rod and the adjustment part would only cooperate over a very short length, insufficient to take up the bending forces.
    Preferably, to ensure sufficient flexural strength, the upper safety section extends over a length corresponding to at least three times the coarse adjustment pitch.
    According to one example, the fixing base comprises a fixing plate provided with holes for fixing it to the structure to be doubled.
    According to one example, the means for fixing to the lining framework comprise clip-on sliding connection means of the connecting piece with a profile, in particular a notch formed on the connecting piece and adapted to receive re-entrant edges of the profile to the way of a clip.
    According to an example, the device bracing includes a first and a second jaw to the outskirts of the stem, and of means of locking with axial tightening both jaws against each other, , of
    so that it pinches between them, after locking, the membrane at the periphery of its skewer opening on the rod. The air tightness function provided by the membrane is thus restored and / or perpetuated.
    According to a example, the jaws present, after locking, a continuous and closed mutual contact zone on herself. According to a example the device bracing
    comprises means for immobilizing the second jaw in translation at least in the direction of the structure to be doubled.
    These immobilization means can for example comprise an axial stop arranged on the rod to oppose the depression of the second jaw in the direction of the structure to be doubled.
    According to one example, the first jaw is formed by the connecting piece.
    According to one example, the second jaw is formed by a washer disposed at the periphery of the rod. The washer can for example be mounted on the periphery of the rod or be in one piece with the rod.
    According to one example, the connecting piece cooperates with the front end of the rod by means of a quarter-turn assembly system of the bayonet type.
    According to one example, the connecting piece has at least one assembly rib, and the rod has at its front end at least one assembly groove comprising an engagement section extending axially and a circumferential section extending from said engagement section, and adapted to cooperate with the assembly rib during quarter-turn rotation, the circumferential section having a narrowing in width away from the engagement section, whereby the assembly rib is gradually tightened in the assembly groove as the quarter turn rotates. As the rotation progresses, the operator feels increasing resistance which indicates the progress of the assembly.
    According to one example, the circumferential section comprises an end of travel stop with which the rib of the connecting piece can come into contact at the end of the rotation. Contact between the rib and this end of travel stop identifies the end of the assembly.
    According to one example, the connecting piece has a central opening through which it is adapted to be assembled on the rod and at least one flexible fin projecting into said opening, said fin being adapted to snap into a groove in the rod, in particular by producing a sound, when the connecting piece is assembled on the rod. The latching of the fin in the groove of the rod is for the operator a witness to the correct assembly of the connecting piece on the rod.
    According to one example, the bracing device further comprises a mechanism for fine adjustment of the positioning of the connecting piece on the rod, in the axial direction.
    According to one example, the fine adjustment mechanism is staggered according to a fine pitch p less than the coarse pitch P, in particular according to a fine pitch p of between 0.1 and 5 mm, in particular between 0.2 and 2 mm, and more particularly between 0.5 and 1.5 mm.
    According to an example, the rod is provided, at its front end, with a fine adjustment section provided at its periphery with a plurality of primary ribs, and the connecting piece is provided with at least one secondary rib adapted to cooperate with the primary ribs of the rod for locking in translation of the connecting piece relative to the rod.
    According to one example, the distal end of the rod is adapted to plug in a membrane. It advantageously has a point shape, useful especially when the membrane is not pierced prior to skewering.
    According to one example, the connecting piece is provided with gripping means at its periphery, in particular with a plurality of notches, for example semi-circular, distributed regularly in the circumferential direction.
    This presentation also relates to a doubling of a structure, comprising a plurality of bracing devices as defined above,
    - At least one layer of thermal and / or acoustic insulation plugged in or inserted between the bracing elements, and at least one membrane plugged in on the bracing devices.
    The membrane is advantageously an air tightness and / or water vapor management membrane, preferably a membrane ensuring both these functions. The water vapor management membrane is advantageously a vapor barrier membrane or a humidity-regulating membrane, that is to say the permeability to water vapor varies as a function of the ambient relative humidity.

    DETAILED DESCRIPTION OF EXAMPLES OF EMBODIMENT
    A bracing device 100 according to the invention is intended to be used in particular for the lining of a frame C, as shown in FIG. 7.
    In known manner, the lining of a frame C comprises a plurality of bracing devices 100 fixed to the rafters CH of the frame C, an insulation gasket G plugged into the bracing devices or interposed between the devices bracing, at least one membrane M, and a lining framework in the form of fixing profiles F for facing plates R. The membrane M is generally an air sealing and / or vapor management membrane water. It may in particular be a vapor barrier membrane or a moisture-regulating membrane, that is to say one whose permeability to water vapor varies as a function of the ambient relative humidity.
    In the particular example illustrated in FIG. 7, the frame C to be doubled is a single-pan roof, having a height difference ΔΗ of approximately 15-20 cm between the top and bottom of the ramp.
    Over the entire width of the ramp, the doubling is here carried out with bracing devices 100 according to the present invention, each adjusted to a different suitable length, as will be described in more detail below.
    A bracing device 100 according to a first embodiment of the invention is illustrated in FIGS. 1 to 6. It comprises:
    a main body 10 comprising o a rod 20 extending along a first axis XI defining an axial direction,, o at the rear end 20b of the rod 20, a base 40 for fixing to the frame C, and a connecting piece 60 provided with means for fixing to the lining framework F, adapted to be assembled at the front end 20a of the rod 20.
    In the example, the bracing device 100 further comprises a washer 70 at the periphery of the rod (mounted at its periphery or in one piece with the rod), intended to cooperate with the connecting piece 60 to restore and / or perpetuate the sealing function of the membrane M plugged into the rod 20 as will be described in more detail below.
    The rod 20 is here provided with a pointed front end 20a allowing the piercing of the membrane M when it is plugged into the rod 20. In this particular example, the membrane M is in fact not pierced prior to the skewering.
    In the present description, the rear of a part is designated as its side closest to the structure to be doubled, and the front of the same part, as its side closest to the lining framework, in position Assembly.
    According to the invention, the bracing device 100 comprises a mechanism for adjusting by steps the length L of the body 10, making it possible to adapt this length L and therefore at the same time the spacing between the fixing means
    of the base of fixing 40 and the piece of fitting 60, at the expected height dubbing. For example, the length L of body 10 may vary thanks to the mechanism of setting of a value understood between 5 and 20 cm.
    The length is adjusted by relative sliding of the fixing base 40 and of the rod 20 in the axial direction XI, then locking in axial translation by relative rotation of the two parts 20, 40. The locking in translation is done in one of several possible adjustment positions, staggered according to a coarse pitch P of between 0.5 and 5 cm, preferably between 0.5 and 2 cm, even more preferably between 0.8 and 1.3 cm, for example equal to 1 cm , as described in more detail below.
    The rod 20 typically has a total length LI of between 20 and 40 cm. It is for example made of a polymer material, for example polyamide, optionally reinforced internally by a metallic core.
    Over most of its length L1, and in particular over its rear portion, the rod 20 has a central part 22 of circular section with constant diameter.
    On its rear portion, the rod 20 is provided, at the periphery of this central part, with a plurality of pins 24 regularly spaced apart from the pitch P.
    In the particular example shown, the rod actually comprises two diametrically opposite rows of identical or similar pins 24, axially aligned and regularly spaced apart from the pitch P (here ten for each row).
    Between these two rows of lugs 24, the rod 20 also has two diametrically opposite grooves 26, each of them being straight and continuous up to the rear end of the rod, and extending in the axial direction XI. Only one of these grooves 26 is visible in FIG. 1.
    As illustrated in FIG. 1, the rod 20 also includes a plurality of grooves 28 extending in the same circumferential direction from each axial groove 26. These grooves 28, called circumferential grooves, are parallel to each other and spaced apart from the pitch P, and they are axially offset with respect to the above-mentioned lugs 24, by a distance for example equal to P / 2 (in the example, a lug is respectively centered axially between two circumferential grooves 28).
    Note that by groove / circumferential groove section (le) is meant in the present description a groove or a groove section extending over all or only part of the circumference of the element carrying said groove.
    The fixing base 40 comprises, in the example, a fixing plate 42 provided with holes 44 for its fixing by screwing to the structure to be doubled. The fixing plate has a length L2 for example of between 5 and 15 cm.
    Advantageously, it can have at least one oblong hole 44a as illustrated in FIGS. 1 to 3, allowing fine adjustment of the positioning of the fixing base 40 on the rafter of the frame.
    The example of the screwing plate 42 is not, however, limiting, the means of fixing to the structure to be doubled can take other forms, for example means suitable for fixing by nailing, or alternatively notches adapted to cooperate. by clipping with a profile previously fixed on the structure to be doubled, in particular adapted to receive flanges returning from said profile. It can be metal profiles, preferably in C, applied to the structure to be doubled (masonry wall or structural elements) with the bottom of the C facing the structure to be doubled and the opening of the C facing the doubling to to receive. The means of fastening to the structure can also take another form which can be plugged in or snapped on with a corresponding form on a slat or other profile attached to the structure to be doubled.
    The fixing base 40 is also provided with an adjustment part 46 of tubular shape extending along a second axis X2 and secured to the means for fixing to the structure to be doubled, here the fixing plate 42. The adjustment part 46 here forms a hollow tube adapted to internally receive the rod 20, the axes XI and X2 then being combined. It comprises for this a central part 48 of circular internal section, of diameter slightly greater than that of the rod, and two diametrically opposite housings 50a, 50b opening on said central part 48 and extending axially, intended to receive the pins 24 of the rod 20 in a first angular position.
    As illustrated in FIG. 1, the adjustment part 46 is provided, on its central part 48, with a plurality of notches 52 aligned in the axial direction and spaced apart by the pitch P.
    More particularly, the adjustment part 46 here comprises two rows of twelve notches 52, diametrically opposite, respectively.
    In the example, the notches 52 are through holes, which allows the installer to view the setting. In a variant, however, the notches 52 could be formed by non-through recesses made on the internal wall of the adjustment part 46.
    At the same time, the adjustment part 46 has (see FIG. 3A), in the vicinity of its front end, two internal thickeners 54 diametrically opposite and dimensioned to slide each in one of the axial grooves 26 of the rod 20 when the rod 20 and the adjusting part 46 are in the first angular position. The two extra thicknesses 54 are spaced from the notches 52 closest to the aforementioned distance P / 2.
    In the first position, the rod 20 is adapted to slide axially in the adjustment part 46, so as to adjust the total length L of the body 10.
    Relative rotation of the rod 20 and the fixing base 40 is permitted when each lug 24 of the rod 20 located inside the adjustment part 46 is positioned axially opposite a notch 52 of this same part 46 , and that each internal allowance 54 of the adjustment part 46 is positioned axially opposite one of the circumferential grooves 28 of the rod 20. The corresponding positions are called, in the following, adjustment positions.
    In these adjustment positions, the rod 20 and the fixing base 40 can pivot, in a direction of rotation, so as to cause the lugs 24 of the rod 20 to penetrate into the notches 52 of the adjustment part 46.
    It is understood that in any other relative axial position of the two parts, rotation is impossible, the extra thicknesses 54 of the adjustment part 46 abutting against the walls of the axial grooves 26, and the pins 24 being retained in the housings 50a, 50b of the adjustment part 46.
    The rod 20 preferably has an upper safety section 30 devoid of circumferential grooves 28, advantageously extending over a length L3 corresponding to at least three times the coarse adjustment pitch P. In the example illustrated in FIG. 1, the length L3 is equal to four times the coarse pitch P: the first circumferential groove 28 is located between the fourth and the fifth lug 24, starting from the rear end 20b of the rod 20. Thus, the pivoting towards the second angular position is only authorized when at least the first four pins 24 have entered the adjustment part 46. Thanks to these provisions, it is avoided that the installer fixes the rod 20 on a number of pins 24 insufficient to take up the forces of bending to which the bracing device 100 is subjected in operation.
    The fixing base 40 and the rod 20 are held in position after adjustment of the length L of the body 10 by means of locking in rotation of the two elements in the second angular position.
    These blocking means here include mechanical means with stop, and more particularly clip means, which will be described in more detail below.
    In the remainder of this description, the locking notches 52a denote the notches having a rotation locking function and the intermediate notches 52b the notches ensuring exclusively a locking function in translation.
    In general, any notch forms a housing extending in a circumferential direction, and having, in this direction, a first end 31a by which a lug 24 of the rod 20 deviating from the first angular position penetrates into the notch, and a second end 31b towards which the same lug 24 points during the rotation from the first to the second angular position.
    As illustrated in FIG. 3A, an intermediate notch 52b is generally delimited, in the axial direction, by two walls 32a, 32b orthogonal to the axis X2 and spaced at a distance equal or very slightly greater than the length of a lug 24 measured in the axial direction.
    As illustrated in FIG. 3B, a locking notch 52a is delimited by a fixed wall 33a, and, in the example, by a clip tab 34, fixed by a proximal end 34a at the level of the first end 31a of the notch 52 and extending in a circumferential direction to its opposite distal end 34b where it is free.
    A free space 35 located on the side of the tongue 34 opposite the notch allows the tongue to move towards said side under the pressure exerted by the lug 24 moved in the notch during a rotation from the first to the second angular position .
    The tongue 34 also has elasticity properties allowing it to automatically return to its initial position where it forms a non-return stop for the lug, once the second angular position has been reached.
    As illustrated in FIG. 3B, the clip tab 34 defines with the opposite wall an engagement section 36 comprising a progressive throttle 36a of minimum width less than the length of a lug 24 measured in the axial direction. For this, the tongue 34 has an engagement ramp 34c and the opposite wall has an engagement ramp 33c, the two ramps gradually converging towards one another.
    Beyond this constriction 36a, the engagement section 36 is extended by a blocking section 37 adapted to receive the lug 24 once the second angular position is reached.
    In the example, the device 100 further comprises means allowing the return to the first angular position under the effect of a relative rotational movement of the rod 20 and of the fixing base 40, or of the combined effect of a relative translation and rotation of the rod 20 and the fixing base 40, as explained below.
    For this, as illustrated in the figure, the tongue 34 includes in the blocking section 37 an unlocking ramp 34d, and the opposite wall 33 likewise has an unlocking ramp 33d, the two ramps 33d, 34d converging the one towards the other in the direction of the engagement section 36. Alternatively, the tongue 34 may not include a release ramp 33d or 34d.
    Advantageously, as illustrated in FIG. 1, only certain notches 52, generally located at the ends of the adjustment part 46, are provided with clipping means. Thus, the force necessary for unclipping is not too great and the blocking is reversible. If the installer is wrong in adjusting the length, he can easily retract the blocking a posteriori and adjust the length again. Clipping, by the sound it produces, also allows the installer to ensure that the rotation is complete and that the rod is correctly secured to the fixing base.
    The front part of the bracing device 100 will now be described in more detail.
    The connecting piece 60 is attached to the front end 20a of the rod 20 and for this has a central fitting opening 62. Advantageously, it cooperates with the front end 20a of the rod 20 by means of a system of bayonet type, turn-by-turn assembly.
    As illustrated in FIG. 6, the connecting piece 60 has two diametrically opposite joining ribs 64 projecting in the vicinity of its fitting opening 62.
    As illustrated in FIG. 4, the rod 20 correspondingly comprises, at its front end 20a, assembly grooves 80 each comprising an engagement section 82 extending axially and a circumferential section 84 extending from said section 82, and adapted to cooperate with an assembly rib 64 during the quarter-turn rotation.
    Each circumferential section 84 has a narrowing in width away from the engagement section 82, so that the assembly rib which is housed therein is progressively tightened as the quarter turn rotates.
    Advantageously, each circumferential section 84 further comprises an end of travel stop 86 with which the rib of the connecting piece comes into contact at the end of the rotation.
    As illustrated in Figure 6, the connecting piece 60 also has two flexible fins 66 projecting into the fitting opening 62, said fins 66 being adapted to snap into corresponding grooves 88 of the rod 20, in particular by producing a sound, when the connecting piece 60 is assembled on the rod 20. This sound allows the installer to ensure that the connecting piece is properly mounted.
    The connecting piece 60 fulfills a first function of assembling a profile of the lining frame with the bracing accessory, for fixing the lining facing.
    As is well known, such a profile (also called a batten or fur), is generally metallic and has a C section with re-entrant flanges pointing towards one another.
    The connecting piece 60 is advantageously provided with at least one notch 67 adapted to receive these edges and cooperate with them according to a sliding connection.
    In the example illustrated, the notch 67 is continuous circumferential and closed on itself. To facilitate snap-fastening, the connecting piece 60 has a convex front face 68 which acts like a ramp to force the elastic spacing of the branches of the profile.
    The membrane M is, due to its connection to the rod 20, perforated around the bracing device 100. As explained above, a connection opening through which the rod 20 passes is in fact created, either by connection, as in the example illustrated here, either prior to skewering. This opening being liable to compromise the air-tightness function of the membrane M, means may however be provided to restore and / or perpetuate the integrity of the sealing function of this membrane M.
    These means here comprise two annular jaws surrounding the rod 20 and locking means with axial clamping of these two jaws against each other, the two jaws pinching together, after locking, the membrane M at the periphery of its opening skewer concerned. A similar system is already described in detail in application WO 2009/103911.
    One of these two jaws is in this case constituted by the connecting piece 60.
    The other jaw is constituted by the washer 70, illustrated more in detail on Figure 5. A annular groove 90 is spared sure The end before 20a of the rod 20. In the example illustrated, the groove annular 90 is space delimited by of them flanges
    parallel, one front 92, the other rear 94, formed at the periphery of the rod 20.
    The washer 70 has a central fitting opening 72 bordered by two clipping tongues 74 adapted to cooperate with the front flange 92 of the rod 20.
    The rear flange 94 forms an axial abutment opposing the insertion of the washer 70 in the direction of the frame C. The front flange 92 forms a stopper opposing the extraction of the washer by the front end of the rod.
    During assembly, the washer 70 is fitted onto the rod 20 after the insulating layer has been plugged into the rod. The washer 70 is force-fitted to cross the front flange 92 of the rod, the edge of its central fitting opening 72 bearing against the rear flange 94.
    The membrane M is then plugged into the end of the rod 20 and pressed against the washer 70 and the layer of insulation.
    The connecting piece 60 is in turn fitted on the end of the rod 20 and compresses the membrane M against the washer 70. When the connecting piece 60 is duly assembled on the end of the rod, the membrane M is pinched by the washer 70 and the connecting piece 60.
    This pinching takes place here on a continuous mutual contact zone closed in on itself. In this case, this contact zone is, like the jaws, annular. However, it is possible, as a variant, to provide other shapes of jaws forming, in their zone of mutual contact, a complete loop of any shape other than circular, for example, polygonal, oval, etc.
    The membrane M is then held behind the profile, away from the lining facing. A free space is thus provided between the lining facing and the membrane and it is then possible to install in this space cables, pipes or equipment without damaging the membrane.
    According to a variant not shown, the insulation lining can be provided with an integrated vapor barrier, which is pierced during the skewering of the lining. In order to restore the airtightness function, a pre-drilled membrane, with lateral dimensions substantially smaller than those of the lining, can be fixed, in particular adhesive, to the vapor barrier. The membrane is pre-drilled and therefore has a skewing opening allowing the passage of the rod without tearing the membrane. The membrane is then pinched at the periphery of the skewer opening between two jaws. Advantageously, one of the jaws is formed by the connecting piece 60, while the other jaw is formed by a washer surrounding the rod and preferably formed integrally with the rod, the lateral dimensions of the washer being greater than those of the skewer opening of the membrane.
    Figures 8 to 10 illustrate a bracing device 200 according to a second embodiment of
    The invention.
    In this embodiment, the rear part of the bracing device 200 is in all respects similar to that described in connection with the first embodiment and the preceding figures. It is therefore not described again in detail.
    It is by its part before the device 200 differs from that of FIG. 1.
    The bracing device 200 here comprises a fine adjustment mechanism for positioning the connecting piece 160 on the rod 120, in the axial direction XI.
    This fine adjustment mechanism is for example staggered according to a fine pitch p less than the coarse pitch P, in particular according to a fine pitch p between 0.1 and 5 mm, in particular between 0.2 and 2 mm, and more particularly between 0, 5 and 1.5 mm.
    As illustrated in FIG. 8, the rod 120 is here provided, at its front end 120a, with a fine adjustment section 180 provided at its periphery with a plurality of primary ribs 182, regularly spaced from one another, parallel between them, and orthogonal to the axial direction XI.
    In the particular example shown, the rod 120 (with its ribs) is truncated on two truncated primary angular portions 184, diametrically opposite, each truncated primary angular portion extending at an angle strictly greater than 90 degrees, for example but not limited to between 120 and 150 degrees. Between these truncated primary portions are defined non-truncated primary portions of the rod.
    The connecting piece 160 is for its part provided with a plurality of secondary ribs 164 protruding into its fitting opening 162 and adapted to cooperate with the primary ribs 182 of the rod 120 for the translational locking of the connecting piece 160 with respect to the rod 120.
    According to one example, the secondary ribs 164 are truncated on two angular sectors 166 of angle greater than the angle of the non-truncated primary portions 186 of the rod, and diametrically opposite.
    The connecting piece 160 is thus free to slide along the rod section 180, in the axial direction XI, when its secondary rib portions 164 are opposite the truncated portions 184 of the rod 120 and its truncated portions 166 are opposite the non-curved portions 186 of the rod, carrying the rib portions (unlocked position illustrated in FIG. 10). Conversely, the connecting piece 160 is blocked in translation in the axial direction XI along the rod 120 when its portions of secondary ribs 164 are opposite the non-truncated portions 186 of the rod 120, and that its truncated portions are opposite the truncated portions 184 of the rod (locked position of the plate illustrated in FIG. 9).
    As in the previous embodiment, two return wings 5 of a profile F can snap into a groove 167 formed on the connecting piece 160.
    The connecting piece 160 here comprises an extension forming a lever 169, adapted to come into abutment on the profile F in the locking position of FIG. 9.
