    [0001] The present invention relates to a plug connection for fluid lines comprising two coupling parts that can be fitted together, which in the plugged state can be removed removably via a locking device, which one side consists of two radially flanged external retaining webs of the two axially adjacent coupling parts in the direction of engagement in the plugged-in state, and on the other hand it consists of a retaining part with a closed ring contour in accordance with with the circumference, which in a pre-assembled state can be pre-assembled, fixed axially and radially in one of the two coupling parts, and in the assembled state, it axially and radially covers the two retaining souls of the two parts of coupling with at least one radially movable radial retention section that has two C-shaped collars on the axial section.
    [0002] In addition, the present invention relates to a non-retaining part for such a plug connection.
    [0003] A similar plug connection as described above is known from WO 2006/018384 A1, in which it is based on a known locking principle, according to which a C-shaped retaining section of a part of retention covers and thereby retains retaining souls of zipped coupling parts due to shape. In order to reduce the risk of losing the retaining part, and to simplify assembly, particularly in application cases, where only a small space of the environment is available at the installation site, or where the coupling parts must be At least one valve is integrated, in this case, it is provided that the retaining part is carried out in such a way and in which one of the two coupling parts is pre-assembled or can be pre-assembled in such a way that, on the one hand, it is fixed axially with little play and radially secure against loss and, on the other hand, it is radially elastically mobile in the area of the retaining section. In this case, the retaining part in the area of the retaining section, as well as the retaining core of the other coupling part, are carried out in adaptation to each other, to form a plug-in connection with closure due to the shape acting in the direction in such a way that, during the engagement of the coupling parts of the retaining section through the retaining core that moves in relation to it, it is moved radially outwards and then in the engaged state due to the radial movement back inwards it covers the retaining souls of the two retaining parts for the lock. Preferably, the retaining part is made as an annular part in a single piece, which has an axial and radially continuous slit interruption at a point on the circumference. This well-known plug connection enables simple, quick and comfortable one-hand assembly, as well as a very safe one. In order to reduce the risk of loss when the retaining part is detached from the coupling parts, WO 2006/018384 A1 provides for connecting the retaining part with one of the coupling parts securely against loss, through an additional safety element , especially in the form of tape or string, at one end on the coupling part and which can be attached at the other end to the retaining part.
    [0004] A plug connection of the type mentioned at the beginning is known from WO 2009/156399 A1. In this document, the additional security element is seen as disadvantageous. In order to forego an additional security element of this type, obtaining that with a small risk of loss of the retaining part at reduced expense, positioning of the retaining part is facilitated and reassembly is planned to execute the retaining part in an annular manner , the retaining part having an annular contour closed according to the circumference, in a pre-assembled state and in the assembled state involves at least one of the two coupling parts. In this case, preferably, the retaining part can be pre-assembled securely in a plug part, and it can be fixed in two positions, in the pre-assembly position and in the assembly position. Through a radial displacement, it is possible to go from the pre-assembly position to the installation position, or through a displacement in the opposite direction to dismantle the installation position back to the original position. In this case, a shape configuration is particularly preferred, in which an annular opening surrounded by the annular contour seen in the cross section is formed from a first partial opening of circular shape with a central point in the area of the retaining section, and a second opening partial circular shape, the central point of which is located within a safety section of the retaining part, with the two partial openings penetrating. In this way, the retaining part must have an extended radial extension, which can be seen as disadvantageous, when only very little mounting space is available.
    [0005] The present invention has the task of perfecting a plug connection of the type mentioned at the beginning, as well as a retaining part for a plug connection of that type, which with the maintenance of the advantages of the known blocking principle, as well as the danger of small loss for the retaining part, the assembly and disassembly can be further facilitated, and in fact particularly also in application cases, where only a very small ambient space is available at the installation site, especially for disassembly small.
    [0006] According to the invention this is achieved by the fact that the collars of the retaining part are executed with different size and / or shape, such that in the case of a radial elastic movement of the retaining section out of the state of assembly , a collar that in the state of assembly abuts the retaining core of the first coupling part releases that retaining core of the coupling part, while the other collar still grips at least partially the retaining core of the other coupling part from behind , which he touches. In this case, it can be provided in particular that one of the two collars has a cam-shaped shoulder, passing in accordance with the circumference, preferably inwardly curved, additionally radial, through which it differs in size and shape from the other collar and around which - seen in the axial direction - it protrudes from the other collar.
    [0007] On the one hand, when connecting the plug according to the invention, the advantages of the generic locking principle combined with the advantages of a plug-in principle are known. If the retaining part is pre-assembled securely in the first coupling part, the other coupling part only needs to be axially plugged for assembly, which allows automated, single-handed, quick, comfortable and safe assembly .
    [0008] On the other hand, in this case, due to the conformation according to the invention, in the loosening of the connection no radial displacement has to be carried out, covering a lot of space for the disassembly of the retaining part, which is of special advantage in assembly sites with only little room space in the radial direction.
    [0009] In this case, preferably through a drive or compression on a pressure surface or through pulling or levering with a tool by applying it to an elastic area that, according to the circumference is located between two retention areas, an expansion can be produced radial in the retaining part, which is sufficient to remove a coupling part from the re-axial connection. In this case, the retaining part according to the invention preferably by means of cam-shaped shoulders in a larger collar of the two collars of the retaining section can remain fixed axially in an annular groove of the coupling part, which still grips behind the retaining core of the other coupling part, on which it touches in the state of assembly, and thereby be fixed.
    [00010] Other characteristics of advantageous conformations of the invention are contained in the subordinate claims, as well as in the following description.

    [00038] For the description below it is expressly emphasized that the invention is not restricted to the examples of execution, and in this case, it is also not restricted to all or to several characteristics of combinations of characteristics described, on the contrary each individual partial characteristic of each example of execution also in particular all other partial features described in connection with this have an inventive meaning in themselves and also in combination with any characteristics of another example of execution.
    [00039] In the various Figures in the drawing, equal parts are always provided with the same reference numbers, and for this reason they generally need to be described respectively only once.
    [00040] A plug connection 1 according to the invention, which can preferably be used for the connection of fluid lines comprises two coupling parts 2, 3, which in the state of assembly shown in Figure 1 are fitted together, and in that state they can be removed removably by means of a locking device 4. In the case of the two coupling parts 2, 3, which can be fitted, this is in particular a part of the sleeve 2 and a part of plug 3, which can be fitted axially (axis XX) with a rod of plug 30 sealing in a receiving opening 20 of the sleeve part 2 and there in the plugged state it is fixed by means of the locking device 4. The two coupling parts 2, 3 can preferably be made of synthetic material.
    [00041] The locking device 4 in this case consists of two external radial retaining cores 21, 31, in the shape of a flange of the two coupling parts 2, 3 and axially adjacent in the direction of engagement (arrow S) in the plugged state and , on the other hand it consists of a retaining part 5. The retaining part can also be made especially for use at lower fluid pressures with advantage as a molded part of synthetic material, and, for example, it can also be used a thermoplastic elastomer material.
    [00042] For the sealing of the plug connection 1- as shown in Figures 1, 3, 7, 8 and 9 - an annular groove 32 may be provided, preferably in the stem of the plug 30, in which a peripheral seal may be inserted not shown, in the form of a sealing ring.
    [00043] The retaining part, which is represented in Figures 1 and 2, 4a and 4b, as well as, from 5 to 12 in a first execution, presents a closed ring contour according to the circumference, not designated in more detail, and in a pre-assembled state shown in Figure 7 it can be fixedly mounted, fixed axially and radially to one of the two coupling parts 2, 3 - in the configurations shown in the plug part 3. For this purpose, an elastic expansion can occur spring, then a disconnection of the retaining part 5 on the coupling part 2, 3, and an inverse elastic spring deformation after the ring. The ability to not get lost from the retaining part 5 in this case is ensured by the closed annular shape. Advantageously, an additional safety element is not necessary because the retaining part 5 surrounds one of the coupling parts 2, 3 with a 360E angle, so completely.
    [00044] From the representation of the state of assembly shown in Figure 1, in this case, it is concluded that the retaining part 5 has at least one radially movable radial retaining section 53 which has two C-shaped collars 51, 52 in the section axial, which, after assembly, axially and radially grips the two retaining webs 21, 31 of the two coupling parts 2, 3 with closure due to the shape. In all the embodiments shown, two retaining sections 53 (see Figures 2.4a, 4b, 10 to 12) are symmetrical with respect to a longitudinal axis Y1-Y1 of the retaining part 5, located diametrically opposite each other in a transversal axis Y2-Y2, however, however, a large number of retention areas can also be present due to an optional segmentation according to the circumference.
    [00045] An exemplary execution of the first upper collar 51 of the retaining section 53 in Figures 1, 2 and 5 can be seen very clearly from Figure 4a, and an exemplary execution of the lower second necklace 52 in Figures 1, 2 and 5 can be seen from Figure 4b. In all the embodiments shown, there are respectively two retaining sections 53, located diametrically opposite each other with collars 51, 52 of this type, as is particularly illustrated in Figures 5, 6, 15, 17, 19 and 22 to 25, through respective individual representations in perspective of the various executions of the retaining element.
    [00046] The second collar 52 of each of the retaining sections 53 of the retaining part 5 is made as a locking element with an internal radial inclined surface 54, which can be made preferably convex, and is located on the side facing the part of glove 2 during the fitting process. If - as shown in Figure 7 - the plug part 3, in which the retaining part 5 is pre-assembled, for the assembly that ends with a lock, is fitted along the XX axis in the receiving opening 20 of the sleeve 2, this inclined surface 54 acts as an expansion surface for the retaining part 5 or more exactly for its second collar 52.
    [00047] Due to the fact that the expansion surface 54 slides in relation to a counter expansion surface 22 of the retaining core 21 that acts as a counter element, with the actuation of an assembly force during the fitting around a defined axial assembly path this causes an expansion movement directed radially out of the retaining part 5, transversal to the XX axis around a radial expansion path. After reaching the end of the expansion path, the collar 52 grips the retaining core 21 of the glove part 2 from behind, snapping into place with the shape, with a radial retaining edge 55, such that a connection is formed lockable fitting due to the shape acting in the fitting direction S, as shown in Figure 1. During the fitting of the coupling parts 2, 3, therefore, the retaining section 53 is moved radially outwards through the retaining core 21 which moves in relation to it, and after a subsequent radial return movement inwards it grips locking the retaining webs 21, 31 of the two coupling parts 2, 3 in the C-shaped state.
    [00048] In a particularly preferred embodiment, in this case, a contour of the expansion surface 54 facing the counter-expansion surface 22 can be adjusted to a contour to a counter-contour of the expansion counter-22, facing the surface of expansion 54 such that during the fitting, the expansion path does not change linearly depending on the assembly path, in particular in several assembly stages during fitting, it changes, at least partially, disproportionately, proportionally and / or subproportional. In this way, on the one hand, a mounting force to be applied to the maximum during fitting can be reduced, whereby the ideal characteristic of the mounting force of the mounting path allows to reduce the height of the mounting force peaks that arise during the fitting. On the other hand, it is possible to obtain a uniform distribution of the work to be spent for the assembly throughout the entire fitting process. In this case, with an additional advantage it is also possible to reduce the entire assembly path compared to a design with a flat expansion surface 54, which leads to advantages especially in terms of minimizing the necessary construction space.
    [00049] When connecting plug 1 according to the invention or to the retaining part 5 according to the invention, it is provided that the collars 51, 52 in the retaining section 53 of the retaining part 5 are made with different sizes and / or shapes, such that in the event of a radial elastic movement of the retaining section 53 out of the mounting state a collar 52 which in the mounting state abuts the retaining core 21 of the first coupling part 2 releases that retaining core 21 of the coupling part 2, while the other collar 51 still at least partially grips the retaining web 31 of the other coupling part 3, on which it abuts. This embodiment according to the invention is illustrated especially by Figures 8 to 12. In this case, Figure 12 shows especially the release of the retaining core 21 of the glove part 2, through the second lower collar 52, and Figure 10, as well as Figure 11 shows an arrangement of the first upper collar 52 on the stem 30 of the plug part 3.
    [00050] As the respective representations of individual parts of the retaining part 5 in Figures 2, 4a, 4b, 5 and 6, 15, 17, 20 and 22 to 25 show, the closed annular shape of the retaining part 5 in the state not deformed it may have a basic shape, particularly oval or elliptical, in which the retaining sections 53 are on the longitudinal sides.
    [00051] As shown, for example, in Figures 4a and 4b, the collars 51,52 of the respective retaining section 53 preferably present a sickle shape, such that in the state of assembly they cover the stem 30 of the plug part 3 with closure due to the shape, preferably in the area of a circumferential groove 33 of the plug part 3, and the sleeve part 2 below its retaining core 21, that is, on the far side of the plug part 3 preferably in the area of a groove circumference 23 of the glove part 2. The representation in Figure 3 and in particular the cut in Figure 10 in this case show that in the circumferential groove 33 - in the sense of an advantageous execution, on the one hand reducing the mass and thereby saving material, in this if, however, at the same time, ribs 30a may also be provided on the other hand.
    [00052] For a pre-assembly fixing of the retaining part 5 to the corresponding coupling part 2, 3 preferably the plug part 4 - as shown in Figures 1 and 3 as well as from 7 to 9 - for the formation of the circumferential groove 33, which receives the corresponding radial collar 51 from the retaining part 5, it may have an additional annular fixing web 34. This web may preferably have a diameter, which is greater than the diameter of the web 31. Instead, the web diameter 31 preferably corresponds approximately to an internal diameter of the web 53 in an area of the web. internal surface between collars 51, 52.
    [00053] By comparing Figures 4a and 4b, it can easily be seen that the two collars 51, 52 - seen in the top view - can preferably be made congruently - except for a cam 56 in the form of an eccentric, going from according to the optionally additional circumference, curved inwards slightly radially of the first upper collar 51, around which collar 51 projects in relation to the lower second collar 52. Through this shoulder 56, in the state of assembly, the upper collar 51 covers the plug part 3 through an angle band greater than the second lower collar 52 covers the sleeve part 2.
    [00054] Expressed in another way: a central angle p1, which in the state of assembly is tight between the beginning and the end of the area of the first collar 51 that acts by fixing (Figure 4a) is greater than a corresponding angle p2 of the second collar 52 (Figure 4b). Therefore, the upper collars 51 of the retention areas 53 always extend - therefore, after pre-assembly, after assembly and also during disassembly - through a circumferential angle p1, which is dimensioned with a size that in the expanded state at most, a distance A between the shoulders 56 (see especially Figures 10 and 11 for disassembly) with respect to its opening diameter is always less than the corresponding diameter D2, D3 of the corresponding coupling part 2, 3 - no present case of the diameter D3 of the plug part 3 in the area of its circumferential groove 33.
    [00055] Expressed more generally: the retaining part 5 according to the invention is dimensioned in such a way that one of the two collars 51, 52 has a cam 56 in the form of an eccentric, passing according to the circumference, curved to preferably inside, additionally radial, through which it differs in size and shape from the other collar 52, 51, and around which - seen in the axial projection - it projects in relation to the other collar 52, 51. In the case of existence of two collars 51, 52 respectively, collar 51 extends with the shoulder 56 - both after pre-assembly of the retaining part 5 in one of the two coupling parts 2, 3 and also after an assembly with the two coupling parts 2, 3 and during disassembly of the retaining part 5 - through a circumferential angle p1, at least one coupling part 2, 3 which is dimensioned with a size that in the expanded state to the maximum of the part of 5 distance retention A between the shoulders 56 of two collars 51 which are diametrically opposed is always less than a diameter D2, D3 of the coupling part 2, 3 on which the collar 51 abuts.
    [00056] On the transverse sides of the retaining part 5, elastic drive areas 57, 58 can be formed, which are preferably located according to the circumference, between the collars 51, 52 of the retaining sections 53, in which through a activation or compression on a compression surface 57 pressure arrow p in Figures 1 to 12), or by pulling or levering with a tool by attacking a traction area 58 (traction arrow z in Figures 1 to 12) ) during disassembly, a radial expansion of the retaining sections 53 can be produced, which is sufficient to remove the connection again axial to a coupling part 2, 3 - in the present case the glove part 2.
    [00057] A minimum free distanceB that is located in the cross-axis Y2-Y2, which exists between the corresponding collars 52 during disassembly, in this case is greater than the corresponding diameter D2, D3 of the coupling part - in the present case greater than the diameter D2 of the glove part 2, in the area of its circumferential groove 23. In this case, the retaining part 5 according to the invention, through the cams 56 in the form of eccentrics on the larger collar 51, which still grips the core of retention 31, 21 of the other coupling part 3, 2 - in the present case of the plug part 3 - on which it touches in the mounting state (and also in the pre-mounting state), is fixed and held axially in the ring groove 33 the coupling part 3.
    [00058] The drive areas 57, 58 in this case can preferably form abutments, and when they are moved in the direction of a longitudinal axis Y1-Y1 of the retaining part 5, they abut the coupling part 3 especially on its stem 30 , for example, - as shown in Figure 9 - the drive area 57 which is in the left half of the Figure in the core of the fixing ring 34 of the stem 30 and thus correspondingly limit the expansion movement of the retaining part 5 of according to the invention, therefore its radial expansion or the radial elastic movement of each retaining section outwards. Thus, after eliminating the applied pressure and / or traction load, it is easily possible to spring back the elastic spring from the retaining sections 53 to a position like that which existed before the deformation. As long as the other coupling part 2 has been removed, then the pre-assembly state exists again.
    [00059] The pre-assembly fixing of the retaining part 5 takes place - at least in the execution according to Figures 1 to 12, after an axial push of the retaining part 5 in one piece on the coupling part 3 - through a radial fitting with closure due to the force of its retaining areas 53 on the over the coupling part 3, and through a drive in at least one of its driving areas 57, 58, the retaining part is expanded maximum by separating in the area of their retention areas 53. After pre-assembly, then there is an angle of coverage of the retention areas 53 for the coupling part, which is greater than 90E, with this angle being as the twice the value of the circumferential angle pl represented in Figure 4a.
    [00060] In Figures 13 to 17, a second embodiment according to the invention of a retaining part 5 is shown, in Figures 18 to 22, a third and in Figures 23 to 25 a fourth, fifth and sixth. In the case of these executions (except in the case of third parties), in principle, advantageously, it is basically also possible to carry out the pre-assembly fixing of the retaining part 5 without an axial thrust from the retaining part 5 to the coupling part 2, 3, because the retaining part 5 is constituted either of two individual parts 5a, 5b preferably connected in a removable and / or articulated way (second and fifth execution) or of a single part, which however has at least one lock, which acts preferably with zipper due to shape and / or zipper due to shape, through which its closed ring outline can be opened (fourth and sixth execution).
    [00061] In the case of the second embodiment, the retaining part 5 consists of two individual parts 5a, 5b that can be removably connected to each other via joints 59, which are shown in the assembly respectively separated in Figures 13 and 14 and in Figures 15 to 17. However, it is not necessarily mandatory or provide for a solubility for use according to the determination of a retaining part 5 according to the invention. In the first individual part 5a (Figure 13) in this case there is the C-shaped retention area 53, while the second individual part 5b (Figure 14), which can advantageously be clipped on the first individual part 5a, forms one of the two drive areas 57, 58 preferably the drive area with the pressing surface 57.
    [00062] The joints 59 facilitate the expansion of the retaining part 5, whereby the second individual part 5b can be produced from a less elastic material, therefore, from a material with greater stiffness or with a greater modulus of elasticity. Thus, under an actuation pressure p it deforms less than the corresponding actuation area 57 in the first run.
    [00063] The joints 59 can preferably be made as hinge joints, the hinge bushings 59a being in the first individual part 5a and the hinge pins 59b being in the other individual part 5b of the retaining part 5, in execution It is preferred - as shown especially in Figure 14 - the hinge pins 59b may have a locking head 59c, by means of which they can be fixed to the hinge bushings 59a by means of a simple clip-on fit. This fixation through which the two individual parts 5a, 5b are connected to the retaining part 5 is preferably illustrated by Figures 15 and 16.
    [00064] In the third embodiment of the invention (Figures 18 to 22) the retaining part 5 is similarly made up of two individual parts 5a, 5b that can be connected together by means of hinge joints 59, of which one is shown separately in several views in Figures 18 and 19. The particularity of the retaining part 5 in relation to the second embodiment in this case, consists in the fact that the individual parts 5a, 5b are produced in a two-component injection molding process , Figures 20 to 22, in turn, show the retaining part 5 in several views as a whole. In this case, the first individual part 5a forms a precast from the first component, into or into which the second individual part 5b constituted from the second component is injected. After the injection, preferably the two individual parts 5a, 5b do not adhere to each other, which can be achieved, for example, by applying a corresponding separation medium on the surface of the precast, or by choosing the corresponding material components.
    [00065] In this case, particularly a comparison of the sectional representations of Figures 16 and 21, as well as, the representation in Figure 18 show that in the first individual part 5a, in which the C-shaped retention area 53 is also found. the hinge bush 59a, in turn, is found, however, that this bush is closed on one side, and axially in the closing area - according to the type of a hook - an additional 59d retaining pin is formed, which in the ready state of the material of the second individual part 5b is covered with closure due to the shape. This connection is not removable.
    [00066] As already mentioned, the fourth execution of the retaining element represented in Figure 23 consists of a single part, which has a closure 60, through which its closed annular contour can be opened. This closure 60 is performed as a snap closure, a mushroom-shaped mandrel 60a, which protrudes particularly on the rear side of the pressing surface 57, cooperates with a complementary opening 60b, which is located in a complementary manner. preferably in the area of a cam 56 in the form of an eccentric. With the exception of integrality, two such closures could also be provided, especially in an axial symmetrical arrangement. Closing can be carried out only with closing due to shape or with closing due to force.
    [00067] Also in the case of the fifth execution, the retaining part 5 consists of two individual parts 5a, 5b that can be connected together, of which the first individual part, in turn covers the retaining sections 53, and the second individual part covers the pressing surface 57. The second individual part 5b is executed as a yoke, which is fixed or can be fixed to the first individual part by means of two closures 61 that act as a closure due to the shape. For the manufacture of such fasteners 61 the free ends 61a of the first individual part 5a made as barb can be rotated elastically and can be guided through yoke openings 61b. After turning the ends 61a backwards, the splinter ends block the opening and prevent the individual parts 5a, 5b from loosening from each other, as shown in Figure 24.
    [00068] In the case of the sixth execution of a retaining part 5 according to the invention shown in Figure 25, a latch closure 62 is provided which acts likewise with closure due to the shape. For the manufacture of the lock 62 a latch part 62a can be guided through an opening 62b, which is located in a lock section 62c of the retaining part, which protrudes from the compression surface 57 preferably on the rear side. In turn - similarly as in the fifth embodiment - the latch part 62a is formed by a free end 61a of the first individual part 5a executed in the form of a barb. In preferred alternative form of production the closing mechanism 62a, 62b, 62 in the closed position - as shown in Figure 25 - can already be formed in the prototype process of the retaining part 5, therefore, preferably in a process of injection casting and therefore does not need to be removable.
    [00069] In opposition to all the described embodiments of the retaining part 5 according to the invention, in which on the transverse sides of the retaining part 5 between the retaining sections 53 the elastic actuation areas 57, 58 are formed, the seventh The embodiment shown in Figures 26 and 27 of a retaining part 5 according to the invention relates to a retaining part construction, in which a drive or compression occurs on at least one compression surface 57a - two surfaces of compression 57a (pressure arrows p in Figure 26) - the pressure applied to is located in the plane of movement of the expansion, but in essence, perpendicular to it. In this case, an arc part 70 is used which - as shown in Figures 26 and 27 - are connected or can be connected with the retaining section 53. Since on this arc part 70 the drive deformation is not applied in the horizontal plane Y1-Y1 (Figures 10 to 12), but in the vertical plane xx (Figure 26), the retaining part 5 can advantageously be made shorter in its longitudinal extension in relation to the previously described executions (axis Y1-Y1 ).
    [00070] The same is the case in the eighth execution shown in Figure 28. In this case, a drive wedge 72 is used, which - can be moved in the vertical direction X-X. Preferably, the guide 74 of the drive wedge 72 in the retaining section 53 in this case can be executed as a dovetail guide. Expansion can take place via an inclined plane with a snap function.
    [00071] As already results from the above executions, the invention is not restricted to the represented and described examples of execution, but also includes all the executions that act equally in the sense of the invention, in which the retaining part 5 is pre-assembled in the part of plug 3 and consequently wraps the plug stem 30 coaxially, of course a corresponding pre-assembly of the retaining part 5 in the glove part 2 can also be provided. Therefore, to a pre-assembled building unit, formed of a part retaining bracket 5 and a coupling part 2, 3, as described for the plug connection 1 according to the invention, an independent inventive significance is likewise assigned.
    [00072] At this point, it should also be noted that in kinematic inversion it is also possible to execute an inclined surface corresponding to the expansion surface 54 in the retaining web 22 of the glove part 2, in order to obtain the described optimization of the locking force during the expansion of the retaining part 5.
    [00073] In addition, the coupling parts 2, 3 on their sides which are opposite to the plug connection side have in principle optional connection elements. In the illustrated embodiment, the plug part 3 has a connection chuck 35 for a fluid line (tube or hose). The glove part 2 does not have any specific execution, but it can have a threaded connection piece, however, at least one of the coupling parts 2, 3 can also be formed as preferably the glove part 2, directly ( in one piece) in the specified aggregates.
    [00074] Furthermore, until now the invention is also not restricted to the combinations of characteristics defined in claims 1 and 13, but can also be defined through any and all other combination of defined characteristics of all individual characteristics published in total . This means that in principle virtually every individual feature of the independent claims can be suppressed or replaced by at least one individual feature published elsewhere in the patent application. In this regard, the claims are to be understood only as a first attempt at formulating an invention.
