    [0001] The invention relates to a male fluid coupling element and a coupling comprising such a male element and a complementary female element. A fluidic connection according to the invention is particularly used in the field of the automotive industry. In fact, during the engine test phases of new vehicles, the engines are installed on test benches, on which they are temporarily connected to auxiliary fluid circuits. Once the test phases are completed, the motors are disconnected from these auxiliary circuits to be permanently connected to power supply circuits in the engine compartment of the vehicles. The connections are made using connectors, which are quickly connectable and disconnectable. In known manner, the fluid connections of the engines mounted on test benches comprise a female plastic element which has elastic claws adapted to be hooked on a collar of a tubular plug for fluid passage. The cycles of assembly and disassembly of the motors and the successive operations of coupling and uncoupling of the connectors use the elastic claws of the female element.
    [0002] WO-A-2011/006591 discloses a fluidic connection comprising a female connector element connected to a pipe and a male tubular fluid passage plug. The female member includes resilient claws that retain a flange of the plug. To uncouple the plug and the female element, the operator manipulates tabs arranged around the claws to press the latter and tilt them in a configuration where they are no longer in engagement with the flange of the plug and where the plug can be removed from the female element. This uncoupling is not convenient for the operator because it must maneuver difficult to access parts. In addition, if the operator does not press enough on the locking claws, they may be damaged or even torn in contact with the flange, when removing the plug. To overcome this drawback, the female end of some fittings is equipped with a sleeve which is movable axially and operated to unhook the claws of the flange engaged on the male member to disconnect the connection. This sheath actually pushes the claws outwardly so that the plug can be removed from the female element without the locking claws being hung by the collar. However, the operation of the sleeve is not secured, that is to say that the control member of the movement of the sleeve is not blocked in coupled configuration and a careless operator can uncouple the connection inadvertently or badly use. In addition, this system has the disadvantage that the claws are caused to wear by friction in contact with the flange when they are unhooked in force.
    [0003] It is to these drawbacks that the invention more particularly intends to remedy by proposing a male element of fluid connection that is more robust and more secure. To this end the invention relates to a male fluid coupling element, comprising: a tubular body, which defines a central axis and a distal mouth, and a tubular fluid passage plug, which is arranged coaxially inside the body, which protrudes axially from the body and which comprises a gripping flange of one or more claws of a female element. According to the invention, the male element further comprises: a sleeve, which is axially movable around the plug between a first position, where it is remote from the flange and a second position, where it is close to or abutting against the collar, a member controlling the displacement of the sleeve from its first to its second position, and - a device locking device of the control member, comprising: a first part able to slide inside the body around the tubular plug between a position distal to the first part where it prevents the actuation of the control member and a proximal position of the first part where it does not oppose a maneuver of the control member to move the sleeve from its first to its second position, and - a second part, which is slidable within the body around the tubular plug between a distal position of the second portion and a proximal position of the second portion, which is adapted to cause the first portion of the device from its distal position to its proximal position and which has a distal end accessible to the mouth of the body. Thanks to the invention, the presence of the release sleeve allows to move axially and then radially disengage each claw of the flange before removal of the male member out of the female element. Thus, the claw or claws are not likely to abut against the flange of the plug of the male element when uncoupling and are less solicited in the long term. In addition, the locking ring prevents the operation of the control member in the distal position, which prevents an unintended action of the operator on the control member. To disconnect the coupling, the operator must first bring the male and female elements closer together to push the locking ring back to the proximal position, which is more secure. This makes it possible to avoid unintentional disconnection of the coupling, following an unfortunate action by an operator on the control member. This also allows to move the gripping claws away from the flange of the male element before spreading them to avoid wear of the claws against the flange. According to advantageous but non-compulsory aspects of the invention, a male fluid coupling element may comprise one or more of the following characteristics, taken in any technically permissible combination: the male element comprises an elastic compression member, which is in abutment between, on the one hand, the second part of the locking device and, secondly, the sleeve adapted to ensure the return of the second part in its distal position and the sleeve in its first position. - The control member comprises a lever articulated on the body about an orthoradial axis to the central axis and in that the lever comprises a thrust finger of the sleeve to its second position, which extends through an opening of the first part of the locking device. - The lever comprises a blocking lever of the pivoting lever, which abuts against the first part of the locking device when it is in the distal position. - The sleeve has an outer diameter greater than the diameter of the flange of the plug. - The first part of the locking device is a locking ring and the second part of the locking device is a feeler ring which is axially offset, along the central axis relative to the locking ring, and which is fit pushing the locking ring towards its proximal position. - The feeler ring is movable axially relative to the body without driving the locking ring between its distal position and an intermediate position, where it makes contact with the locking ring. - The element comprises a member exerting an elastic return force of the locking ring in its distal position. - The locking device is a one-piece assembly consisting of a first proximal portion and a second distal portion, the assembly being movable between a distal position where the proximal portion of the locking device prevents the operation of the control member , and a proximal position where the proximal portion of the device does not oppose a maneuver of the control member. The invention also relates to a fluidic connection comprising a male element as described above and a female element comprising at least one claw, having an attachment surface to the flange of the male element. The sleeve is able to release each claw when it is moved from its first to its second position. According to advantageous but not compulsory aspects of the invention: the female element comprises a pusher having a thrust surface of the end of the second part of the locking device, this end being accessible to the pusher at the mouth of the body. - A distance between the gripping surface and the thrust surface is greater than a distance, measured parallel to the central axis, between a locking face belonging to the flange and the contact surface, with the female element, the second part of the locking device in its distal position. - The first part of the locking device prevents the operation of the control member when the engagement surface of the claw is engaged with the flange of the male element. - The control member is operable after approximation of the male and female elements relative to a coupled configuration of the connector. The invention and other advantages thereof will appear more clearly in the light of the following description of several embodiments of a male element, a female element and a fluid connection in accordance with its principle. , given purely by way of example and with reference to the drawings in which: - Figures 1 to 6 are longitudinal sections of a fluidic connection according to the invention and comprising a male element according to the invention, which represent the successive steps of coupling and uncoupling the coupling, - Figure 7 is an enlarged view of the box VII of Figure 1, - Figure 8 is an enlarged view of the box VIII of FIG. 9 is a perspective view of a female element of the fluidic connection of FIGS. 1 to 8, shown with a portion in half-section for better visualization; FIG. 10 is a perspective view; analogous to FIG. 9 shows a female element of a coupling according to a second embodiment, and FIGS. 11 and 12 are longitudinal sections respectively similar to FIGS. 1 and 5 showing a fluidic connection according to a third embodiment. of the invention. In Figure 1 is shown a fluidic connection R in a disengaged configuration. This connection R is adapted to the passage of any type of fluid, whether a liquid or a gas. The fluidic connection R comprises a male element 100 and a female element 200. The elements 100 and 200 are in practice each connected to a pipe which is not shown, for the sake of clarity of the drawing. The male element 100 comprises an outer body 102, which has a generally tubular geometry, centered on an axis X102. Apart from the seals, the constituent parts of the male element 100 are all made of metal. They are also simple to manufacture, resulting in a cheap R connection. In the rest of the description, a "distal" or "front" orientation of a coupling element designates an axial direction facing the complementary coupling element, in the configuration of FIG. "Proximal", or "rear", of a coupling member means an axial direction facing away from the complementary coupling member. For example, in the case of the male element 100, the distal direction is oriented towards the female element 200, while the proximal direction is turned away from the female element 200. For better identification, the elements arranged distally within a connecting element have a reference followed by the letter "b", while the elements arranged proximally within the connecting element have a reference followed by the letter "a". ". The body 102 delimits a distal mouth 102.1 and an internal shoulder 102b disposed on the side of its distal mouth 102.1. The body 102 also defines another inner shoulder 102a, which is disposed proximally of the shoulder 102b. The body 102 further comprises a passage opening 0102 of a control member 108. A tubular fluid passage plug 104 is disposed coaxially within the body 102 and protrudes distally therefrom. The plug 104 is a plug, which has a flange 104b for hooking with the female element 200. As can be seen in FIG. 7, this flange 104b has a locking face S104b of claws 202 of the female element 200. S104b face is an annular surface disposed on the proximal side of the flange 104b.
    [0004] The male element 100 also comprises a "declawing" sleeve 116, which is adapted to disengage the claws 202 from the female element 200 and which is axially movable under the action of the control member 108. The sleeve 116 is arranged coaxially around the plug 104. It comprises a proximal ring 116a, with which the control member 108 cooperates and a distal end 116b, which is adapted to cooperate with the female member 200. The sleeve 116 is axially movable around the 104 between a first position, where it does not interact with the claws 202 and a second position, where it is able to clear the claws 202 of the flange 104. The first position is a coupling position, while the second position is position is a decoupling position. The male element 100 comprises a device 105 for locking the control member, consisting of a first portion 106 and a second portion 114 slidable within the body 102 around the tubular plug 104. first part of the locking device 105 is a locking ring 106 of the control member 108, which is arranged coaxially inside the body 102. More specifically, the ring 106 is disposed coaxially around the sleeve 116. The ring 106 is adapted to be pushed axially by the female element 200, between a distal position where it prevents the operation of the control member 108, and a proximal position where it does not oppose a maneuver of the control member 108 to move the sleeve from its first to its second position. The locking ring 106 also defines an opening 0106 through which the control member 108 passes. A proximal edge of the opening 0106 comprises a chamfer C106. Furthermore, the locking ring 106 has, on the proximal side, an outer peripheral end ring 106a. 106b is the distal end of the locking ring. The shoulder 102a of the body 102 forms an abutment shoulder of the ring 106a of the locking ring 106 in its forward displacement, under an elastic force E110 exerted by an elastic compression member such as a spring 110. second part of the locking device is a feeler ring or "feeler" ring 114 which is arranged coaxially around the sleeve 116 and has a proximal end 114a adapted to cooperate with the locking ring 106 and a suitable distal end 114b to cooperate with the female member 200 because it is axially offset relative to the locking ring 106 and accessible to the female member 200 at the mouth 102.1 of the body 102. The feeler ring 114 protrudes from the body 102. The feeler ring 114 is arranged axially on the distal side with respect to the locking ring 106 and is able to cooperate with the female element 200 to push back the locking ring. scrubbing 106 to its proximal position. The feeler ring 114 is axially movable in contact with the female element 200 between a distal position, where it does not cooperate with the female element 200, an intermediate position, where it makes contact with the locking ring 106, while distal position, and a proximal position where it is in contact with the ring 106, then itself in the proximal position. In the intermediate and proximal positions, the proximal end 114a of the feeler ring 114 contacts the distal end 106b of the locking ring 106 and the feeler ring co-operates with the female member 200. The feeler ring 114 also defines an internal shoulder 115. In addition, the feeler ring 114 comprises a proximal outer collar 114c.
    [0005] In uncoupled configuration, d1 denotes the distance, measured parallel to the axis X102, between the proximal end 114a of the feeler ring 114 and the distal end 106b of the locking ring 106 and d3 denotes the distance, measured parallel to the axis X102, between the distal end 114b of the feeler ring 114 in the distal position and the locking face S104b of the collar 104b.
    [0006] A spiral spring 118 is interposed between the shoulder 115 of the feeler ring 114 and the ring 116a of the sleeve 116. It therefore comprises a first turn bearing against the shoulder 115 of the feeler ring 114 and a last bearing turn. against the proximal ring 116a of the sleeve 116. This spring 118 is centered on the axis X102 and forms a resilient return means of the feeler ring 114 to its distal position. The spring 118 exerts an elastic force E118 on both the feeler ring 114 and the sleeve 116. The spring 118 also forms an elastic return means of the sleeve 116 in its first position. Furthermore, the feeler ring 114 is stopped in its forward movement by the contact of its flange 114c with the shoulder 102b of the body 102.
    [0007] The control member 108 is a lever, which is articulated about an axis Y108 and which is operable with the thumb. The Y108 axis is orthoradial with respect to the X102 axis. More specifically, the lever 108 is articulated around a shaft 120 mounted on the body 102, which is circular in section and which is centered on the axis Y108. The lever 108 comprises a finger 1084 for pushing the sleeve 116. This finger 1084 extends through the opening 0206 of the locking ring 106 and bears against the proximal ring 116a of the sleeve 116. The lever 108 also comprises a heel 1082 locking the pivoting lever 108, which abuts against the locking ring 106 when it is in the distal position. Specifically, the heel 1082 abuts against the outer radial surface S106 of the locking ring 106. The heel 1082 is square in shape, with rounded fillet.
    [0008] The lever 108 is pivotable between a raised configuration, shown in Figures 1 to 4 and a lowered configuration, shown in Figures 5 and 6. The spring 110 is a return spring of the locking ring 106 in the distal position. It is interposed between the proximal ring 106a of the locking ring 106 and a centering piece 112 of the plug 104 in the body 102, this centering piece 112 being disposed proximally in the male element 100. The centering piece 112 delimits a housing receiving the plug 104. The spring 110 is a spiral spring centered on the axis X102. It comprises a first turn bearing against the ring 106a and a last turn bearing against the piece 112. It exerts an elastic force E110 on the locking ring 106. The female member 200 is generally tubular and centered on an axis X201. The female element 200 is a plastic tip. It comprises a tubular body 201 and two resilient claws 202 which extend distally from the body 201. The claws 202 comprise a distal end portion 202b which projects radially inside the body 201. This part of 202b end is adapted to hook on the flange 104b of the plug 104. As best seen in Figure 9, the end portion 202b of the claws 202 has a proximal attachment surface S202b with the locking face S104b of the flange 104b. Furthermore, the surface S202b of each claw 202 extends in a plane perpendicular to the axis X201 when the claw 202 is not deformed, in particular in the configurations shown in FIGS. 1 to 9. The end portion 202b of the claws 202 has a beveled edge B202, intended to come into contact with the collar 104b at the coupling. This beveled edge allows the claws 202 to deform elastically to overcome the flange 104b during coupling. The female element 200 also comprises a pusher 204, which is tubular and which surrounds the elastic claws 202. This pusher 204 comprises a distal end 204b of the distal end 114b of the second portion 114 of the locking device, which is the scanning ring 114. d2 denotes the distance, measured parallel to the axis X201, between the gripping surface S202b of the claws 202 and the thrust surface 204b belonging to the pusher 204. The female element 200 also comprises a seal O-ring 206, which is disposed in an inner peripheral groove of the body 201. The body 201, the pusher 204 and the claws 202 are in one piece. To couple the connection R, it is first necessary to place the elements 100 and 200 vis-à-vis, aligning the axes X201 and X102.
    [0009] Then, it is necessary to insert a portion of the male element 100 in the female element 200. This movement is shown in Figure 2 by an arrow F1. As shown in this figure, it is impossible to switch the lever 108 in this configuration since the tilting operation R1 of the lever 108 is prevented by the heel 1082 which abuts against the outer surface S106 of the locking ring 106. When one the male element 100 is brought closer to the female element 200, the feeler ring 114 is pushed axially backwards, against the elastic force of the spring 118. In other words, the spring 118 is compressed against the proximal ring 116a of the sleeve 116. The feeler ring 114 is axially movable relative to the body 102 and thus moves from its distal position shown in Figure 2 to its intermediate position shown in Figure 3, where its proximal end 114a is in contact with the distal end 106b of the locking ring 106 without driving it. The race of the ring 114 between these two positions corresponds to a dead race since it does not cause displacement of the locking ring 106. This dead stroke has a length equal to the distance d1. In parallel, the claws 202 of the female element 200 are elastically deformed outwards, in a direction generally radial to the axis X201 and centrifugal, in contact with the collar 104b of the plug 104. As soon as the part of end 202b of the claws 202 has passed the flange 104b, the claws 202 return to their original shape by elastic return, as represented by the arrows F2 in FIG. 3. The gripping surface S202b of the claws 202 then engages on the face of S104b lock of the collar 104b, which prevents the withdrawal of the male member 100 out of the female member 200. The connection R is then in the coupled configuration. The distance d2 between the gripping surface S202b and the thrust surface 204b of the pusher 204 is less than or equal to the distance d1 separating the feeler ring 114 and the locking ring 106 in the uncoupled configuration of the fitting R. As mentioned above, above, this distance d1 corresponds to the stroke of the feeler ring 114 between its distal position and its intermediate position. The female element 200 is designed so that the feeler ring 114 catches up to its maximum clearance dl with the locking ring 106 during coupling. In the example, d1 is equal to d2 so that the feeler ring 114 catches its game dl with the locking ring 106 during the coupling, without moving the ring 106. The coupling of the element male 100 with the female member 200 therefore does not cause displacement of the locking ring 106 backwards and the risk that the locking ring 106 is held proximally in the coupled configuration and therefore never opposes at the operation of the lever, is discarded. This therefore guarantees the safety of the connection of the connection R.
    [0010] Furthermore, the plug 104 is inserted into the body 201 beyond the seal 206, so as to make a tight fluid connection of the male and female pipes. To disconnect the connection R, it is necessary to bring the female member 200 of the male element 100, that is to say to engage more deeply the plug 104 in the body 201, a predefined distance d4. For this, the operator must push the male element 100 further inside the female element 200, as represented by the arrow F3 in FIG. 4. This additional displacement F3 implies that the claws 202 of the female element 200 deviate, or move axially away from the blocking face S104b of the flange 104b. This additional displacement F3 of the male element 100 also induces that the female element 200 pushes the feeler ring 114 which, in turn, pushes the locking ring 106 towards the rear, as represented by the arrows F4 and F4 ' in FIG. 4. The feeler ring 114 thus passes from its intermediate position to its proximal position, against the elastic force E118 of the spring 118 and the locking ring 106 passes from its distal position to its proximal position. against the spring force E110 of the spring 110. The operator must maintain the female element 200 on the front, to prevent the elastic return of the locking ring 106. In the proximal position, the opening 0106 is radial facing the opening 0102 passage of the lever 108, and wherein the heel 1082 is no longer in abutment against the outer surface S106 of the ring 106. The opening 0106 is quite wide and sufficiently far back of the opening 0102 to let pass the heel 1082. The stroke of the ring 106 between its distal position and its proximal position and the stroke of the feeler ring 114 between its intermediate position and its proximal position are therefore equal to the distance d4 of approximation necessary to the release of the lever 108. When the ring 106 reaches the proximal position, it is possible to tilt the lever 108 without the heel 1082 abuts against the outer surface S106 of the locking ring 106, as represented by the arrow R2 in FIG. 4. The locking ring 106 prevents the lever 108 from being actuated until the elements 100 and 200 have been brought closer to the distance d4, which depends on the positioning of the opening 0106 and the shape of the lever 108, otherwise said as the flange 104b of the plug 104 has not been far enough in the body 201 relative to the claws 202. The pivoting movement R2 of the lever 108 around the axis Y108 is facilitated by the presence of the chamfer C106 delimited on the proximal edge of the opening 0106 and the rounded fillet of the heel 1082. It is therefore essential to bring the male element and the female element of the coupling to allow the maneuvering of the organ control.
    [0011] The pivoting R2 of the lever 108 is effected between its raised configuration and its lowered configuration and causes the finger 1084 to push the "declawing" sleeve 116 into its second position, as represented by the arrow F5 in FIG. 5. In the raised configuration of the lever 108, the sleeve 116 is in its first position while in the lowered configuration of the lever 108, the sleeve "declawing" 116 is in its second position. The displacement F5 of the sleeve 116 forwards is against the spring action E118 of the spring 118. In other words, the spring 118 is compressed during the displacement of the sleeve 116 forwards. The distal end 116b of the sleeve 116 is driven towards the flange 104b during the pivoting R2 of the lever 108 and releases the claws 202 of the female element 200 towards the outside, in particular in a generally centrifugal manner, as represented by the arrows F6 at In fact, the bevelled edges B202 of the claws 202 are oriented such that the support of the distal end 116b of the sleeve 116 on the edges B202 causes elastic deformation in a centrifugal overall direction. As explained above, when the claws 202 are disengaged towards the outside, they are kept spaced from the flange 104b of the distance d4, which advantageously allows the gripping surface S202b of the claws 202 not to rub against the face S104b blocking of the flange 104b. This further allows that the sleeve 116 does not come to crush the claws 202 against the flange 104b during its movement between its first and second position. There is therefore no risk of crushing or tearing the claws 202 during the uncoupling and the wear of the claws 202 during the successive operations of connection and disconnection is reduced. The distal end 116b finally abuts the flange 104b. The claws 202 are disengaged and the contact between the sleeve 110 and the flange 104b is maintained so that the male member can be removed without the risk that the locking face S104b of the flange 104b catches the claws upon disconnection. When the male element 100 is withdrawn from the female element 200, the claws 202 return to their initial shape by elastic return, as represented by the arrows F7 in FIG. 6. Furthermore, the distance d2 between the surface of S202b hooks and the thrust surface 204b is greater than the distance d3, measured parallel to the central axis X102, between the contact surface 114b of the feeler ring 114 distal to the female member 200 and the locking face S104b belonging to the flange 104b.
    [0012] Thus, the uncoupling movement of the fluidic connection R is accompanied by the thrust of the feeler ring 114 against the pusher 204 of the female element 200 since the feeler ring 114 is subjected to the elastic force of the spring 118 towards the spring. before, that is to say in the direction of the female element 200. The feeler ring 114 therefore passes from its position proximal to its distal position. The stroke of the ring 114 between these two positions is equal to the value of the overtravel d4 necessary for the release of the lever 108, plus the dead stroke d1. The dead stroke d1 makes it possible to eject the female element 200 under the elastic force of the spring 118. In other words, when uncoupling, the female element 200 is automatically moved away from the male element 100 by a distance corresponding to the length dl of the dead race. The operator therefore does not need to pull the male element 100 to release the claws 202 of the flange 104b, which are remote automatically away from the locking face of the flange without risk of inadvertent reconnection of the connection to the loosening of the lever. The release force claws 202 is mastered by the stiffness of the spring 118. This allows to uncouple the connection R without damaging the elastic claws 202 and automatically. The outer diameter of the sleeve 116 is greater than the outer diameter D104 of the flange 104b, so that the withdrawal of the male element 100 from the female element 200 is done without the claws 202 do not cling to the flange 104b . There is therefore no risk of crushing the resilient claws 202 in contact with the flange 104b during the disconnection maneuver. Once the coupling R is uncoupled, the operator releases the pressure on the lever 108, which then rises automatically by elastic return of the sleeve 116 to its first position, under the elastic force E118 of the spring 118. Similarly, ring 106 returns in distal position under the elastic force E110 of the spring 110. In FIG. 10 is shown a construction variant of a female element 200. The female element 200 of FIG. 10 differs from that of FIG. it does not include a tubular pusher but the tabs 205 thrust of the feeler ring 114. These pusher tabs 205 are supported by the claws 202 and are bent. They comprise a thrust surface 205b, which is intended to come into contact with the distal end 114b of the feeler ring 114. The construction of the male element and the operation of the connection to the coupling and the uncoupling remain similar to what has been described previously. In Figures 11 and 12 is shown a second embodiment of a male member 100 belonging to a fluid connection. In this second embodiment, the elements that are identical with respect to the first embodiment retain their numerical references, while the elements that differ from that of the first embodiment carry other numerical references. The fluidic connection of this embodiment operates generally as that of FIGS. 1 to 9.
    [0013] The male element 100 of FIGS. 11 and 12 differs from that of FIGS. 1 to 6 in that the feeler ring and the locking ring are in one piece and form the same locking device 105. This one-piece locking device 105 comprises a first part 105a, which in distal position, prevents the operation of the control member 108 and a second portion 105b, said proximal portion, accessible to the female member 200 by the mouth 102.1 distal body 102. During the coupling, the distal end surface S105b of the device 105 is therefore pushed axially backwards directly by the female element 200 and against the elastic force E118 exerted by the spring 118. The uncoupling is performed in a similar manner in the first embodiment, that is to say that it is necessary to bring closer the female element 200 of the male element 100 to be able to tilt the lever 108 and advance the sleeve "declawing" 1 16. The sleeve 116 then spreads the claws 202 outwards, as represented by the arrows F8 in FIG. 12. The operator can then remove the male element 100 from the female element 200 without risking catching the claws. 202 by the flange 104b. The elastic return of the device 105 in the distal position takes place under the effect of the force E118 of the spring 118. There is therefore no need to provide an additional spring at the rear of the male element 100, as in the first embodiment. The construction of the connection of Figures 11 and 12 is therefore simpler. In a variant that is not shown, an operating member other than a lever may equip the connection R. For example, the operating member 108 may be an outer ring, operable axially from front to back and acting on an internal lever system rocker to push the sleeve 116. It is also conceivable to use a radial push button, coupled to a wedge system to push the sleeve 116.
    [0014] In a variant that is not shown, the female element 200 does not come into contact with the feeler ring 114 at the coupling. Alternatively not shown the second part of the locking device may not exceed the body and always have an accessible end to the mouth 102.1 of the body.
    [0015] In variant not shown, the feeler ring 114 may be replaced by one or more "feeler" fingers, which have at least one projecting stop, adapted to push the ring 106. According to another variant not shown, the sleeve 116 is close to the flange 104b in its second position so that the sleeve is movable between a remote position and a position close to the collar, without contact therewith.
    [0016] The technical features of the variants and embodiments envisaged above can be combined with each other to generate new embodiments of the invention.
