Description

[0001] The invention relates to an assembly with a component body and a fastening body, which can be connected to each other by a bayonet joint.

[0002] In the prior art, such components as mentioned at the beginning are basically known. These components can be, for example, electrically operated components, such as lamps. It is known that there are a variety of fixing methods that make it difficult or impossible to loosen or remove the component body from the fastening body in the closed or connected working state, especially using one-handed operation. For example, a rope can be provided to keep the component body at the fastening body, even when the bayonet joint is released. Also known are bayonet joints with simple fall protection, but simple fall protection is relatively easy to overcome. It is also possible to install a simple spring lock to prevent the component body from loosening relative to the fastening body, for example by keeping the bayonet protrusion in the bayonet groove pre-tightened toward the locked position. These known fixing mechanisms are either visible and thus not very aesthetically pleasing, or relatively complex and expensive to implement, or easily overcome, so that they are only used for limited fixing.

[0003] It is therefore an object of the present invention to provide an assembly of the type mentioned at the outset which has a simple and effective, preferably aesthetically pleasing fastening mechanism.

[0004] This object is achieved by the subject matter of the independent claim. The dependent claims develop the central idea of ​​the invention in a particularly advantageous manner.

[0005] According to a first aspect, the present invention relates to an assembly having a component body and a fastening body for fastening the component body. The component body can be connected to the fastening body by a bayonet joint of the assembly. The bayonet joint has a bayonet projection (e.g., on the component body side) and a bayonet groove (e.g., on the fastening body side), and the bayonet projection can be guided in the bayonet groove and along the bayonet groove. The bayonet groove has an introduction portion, by which the bayonet projection can be introduced into the bayonet groove along the introduction direction. In addition, the bayonet groove also has a functional portion, which extends laterally away from the introduction portion relative to the introduction direction, and leads to a locking portion for locking the bayonet projection at its far end, in which the bayonet projection can be locked in a locking position. In addition, the bayonet groove also has a blocking portion, which connects the functional portion and the introduction portion together. The blocking portion is preferably located downstream of the introduction portion in the introduction direction, and / or laterally bifurcates from the introduction portion to the functional portion relative to the introduction direction. The bayonet slot also has a pocket extending away from the functional part in a direction opposite to the introduction direction between the blocking part and the locking part, in which the bayonet projection can be at least partially accommodated in the holding position. The assembly also has a blocking element, which can be optionally positioned in the blocking position in the blocking part so as to block the passage for the bayonet projection between the introduction part and the functional part in the bayonet slot. The assembly (e.g., component body) is configured so that the blocking part is at least partially exposed in the holding position so that the blocking element is positioned in the blocking part.

[0006] By means of the above-mentioned component design, a pocket is provided in the bayonet slot, by means of which the component body and the fastening body can be offset relative to the introduction direction by introducing the bayonet projection into the holding position of the pocket, thereby exposing the blocking portion accordingly, so as to position the blocking element therein. By accommodating the bayonet projection in the pocket, the component body and the fastening body can thus be fixed in a safe, preferably suspended position (holding position), thereby simplifying the operation of the assembler. In this position, a fixing device can be provided in the bayonet slot by exposing the setting of the blocking portion, by which the bayonet projection can be blocked from loosening from the bayonet slot, thereby preventing the bayonet joint from separating. Then, the bayonet joint can be closed or fixed by moving the bayonet projection into the locking position and locking it in this position. Then, the bayonet projection only needs to be moved from the locking position into the holding position again, thereby exposing the blocking portion accordingly, for loosening. The blocking effect can be eliminated by removing the blocking element from the blocking portion or the blocking position; due to the holding position, this is preferably adopted in a manner that is convenient for the assembler. Then, the bayonet projection can be introduced into the introduction part through the barrier part exposed again, and then guided out of the bayonet groove, so as to disassemble the assembly. Thus, the corresponding assembly is simply but effectively fixed. The bag-shaped part is preferably used as a folding bag here, which simultaneously fixes the component body and the fastening body relative to each other and makes the barrier part easy to approach, so that the blocking element is positioned in the blocking position or removed from the blocking position. A relatively cheap but safe bayonet joint can be provided by this simple design. In addition, it is also possible to assemble and disassemble easily but safely and conveniently.

[0007] The component body preferably has a bayonet projection and the fastening body preferably has a bayonet slot. In this way, a preferred component design can be provided in which the component body, which usually determines the aesthetic appearance, has a less conspicuous part of the bayonet connection, namely the bayonet projection. This also makes it possible to hide the bayonet connection more effectively. The fastening body can basically also have a bayonet projection and the component body can also have a bayonet slot.

[0008] The blocking element can be arranged (for example at the fastening body) for being optionally movable in a holding position between a blocking position and a release position, in which the blocking element releases a passage for the bayonet projection in the bayonet slot between the introduction part and the functional part. The blocking element can remain in the assembly by the mobility of the setting of the blocking element in the assembly. On the one hand, this simplifies the assembly of the assembly when using a bayonet joint. On the other hand, the blocking element can preferably be provided in a more anti-lost manner. But it is also conceivable in principle that the blocking element is removed or taken off to expose the passage and is fixed accordingly to be positioned in the blocking part.

[0009] The blocking element preferably has a screw or is a screw. This allows a simple component to be provided as a blocking element, which can be operated simply and intuitively. In addition, screws are also easy to provide; thus, standard components can preferably be used. In addition, the receiving portion of the blocking element can also be provided, for example, in the form of a simple internal thread (such as a threaded hole). According to a particularly preferred embodiment, the blocking element is a threaded pin or has a threaded pin. This allows a particularly simple and easy to provide component to be used as a blocking element.

[0010] The screw is preferably designed and arranged to be moved between a blocking position and a release position by turning the screw. A corresponding blocking element can thereby be provided and operated particularly easily. Furthermore, a fastening can thereby be provided by means of a bayonet connection which also meets high safety requirements (for example those specified in DIN EN IEC 60598). For example, it is generally not permitted to loosen or remove in particular a cover or housing with one hand in order to prevent electric shock.

[0011] The blocking element can preferably have a follower thread profile (eg groove, cross recess, hexagon socket, hexagon socket, etc.) so that the blocking element can be screwed into a corresponding thread in a simple manner using common tools or moved between a blocking position and a release position.

[0012] The blocking element preferably has a pressure piece with a movable pressure-bearing part, wherein the pressure-bearing part is preloaded into or toward the blocking position by a compression spring so as to block the passage for the bayonet protrusion between the introduction part and the functional part in the bayonet slot. Thus, a common and easy-to-provide component is provided as a blocking element. The pressure piece preferably has a sleeve, a compression spring and a pressure-bearing part. The pressure-bearing part is accommodated in the sleeve and moves longitudinally between the sleeve bottom (whereby the pressure-bearing part is preferably (basically) completely accommodated in the sleeve) and the relative opening (whereby the pressure-bearing part partially protrudes out of the sleeve through the opening). The compression spring is arranged between the pressure-bearing part and the bottom so as to preload the pressure-bearing part toward the opening. The sleeve has a stopper for the pressure piece in the opening area so as to keep the pressure piece in the sleeve in a loss-proof manner. The sleeve can be provided as a separate component or can be arranged to be integrally formed with a component (such as a component body or a fastening body). The compression spring is preferably made of stainless steel. The pressure-bearing part preferably has a sphere, which is made of stainless steel or polyoxymethylene (POM), for example. For example, the pressure piece (for example its sleeve) can have an external thread (and thus a screw) in order to be accommodated accordingly in the component and to position the pressure part in the blocking position. It is also conceivable that the pressure piece is accommodated in the component with a force fit (for example by self-clamping) in order to (initially) position the pressure part in the blocking position; for this purpose, the sleeve is preferably made of plastic (preferably thermoplastic) so that it can be easily inserted or pressed into a corresponding recess in the component.

[0013] The pressure piece is preferably constructed and arranged so that the pressure-bearing part can be optionally moved from the blocking position into the release position against the preload force of the compression spring; i.e., for example, away from the opening towards the sleeve bottom into the sleeve. In this way, the component body and the fastening body can be easily connected, while the bayonet joint is well fixed by the preloaded pressure piece. Since the pressure piece is preloaded towards the blocking position, it is automatically pushed back into this position, so that the bayonet projection is safely blocked in the above-mentioned channel of the bayonet groove.

[0014] The component body preferably at least partially or completely accommodates the fastening body in the locked position. Thus, the generally functional fastening component (such as the fastening body) can be effectively hidden by the generally functional aesthetic component (such as the component body). This can also achieve a compact structural type.

[0015] The assembly is preferably configured so that the bayonet slot is completely covered in the locked position, preferably by the component body. The bayonet connector is thus concealed in a simple and effective manner in the locked position, while at the same time the effective accessibility of the fixing device of the bayonet connector is achieved by the blocking element.

[0016] The blocking portion preferably branches off from the distal end of the introduction portion relative to the introduction direction; the distal end is preferably located downstream of the introduction direction or transverse to the introduction direction. The blocking portion preferably branches off from the end of the introduction portion opposite to the introduction opening (for the bayonet protrusion to enter the bayonet slot). This provides an overall simple bayonet slot structure, which is easy to manufacture and can be intuitively operated.

[0017] The functional part preferably tapers towards the locking part.In this way a simple and effective connection is provided by the bayonet joint.

[0018] The functional part preferably has a start-up slope which points in the introduction direction and which is inclined towards the locking part in the introduction direction. When the bayonet projection moves into the locking position, i.e. when the bayonet projection is introduced into the locking part of the bayonet slot, the start-up slope enables an intuitive and simple connection of the bayonet joint.

[0019] The component body and the fastening body preferably each have contact surfaces facing each other relative to the introduction direction, wherein the bayonet connection is configured such that the contact surfaces are pressed against each other in the locked position, preferably by supporting the bayonet projection relative to the locking portion or the activation ramp. In this way, a large-area connection surface can be provided between the component body and the fastening body, so as to ensure that the components are effectively connected in the locked position. The activation ramp can preferably be used here to press the contact surfaces against each other in a simple manner in the locked position; the activation ramp can therefore serve as a support for the bayonet projection.

[0020] The activation ramp can thus serve as a support, press the contact surfaces against one another, and / or provide the aforementioned tapering of the locking portion in a simple manner.

[0021] In a preferred embodiment, a preferably circumferentially closed seal can be provided between the two contact surfaces in order to seal the component in this connection region in accordance with the required IP protection class.

[0022] In its protruding direction, the bayonet projection can preferably have a circular or polygonal cross section. For example, the bayonet projection can preferably be configured as a pin or a block. In general, the bayonet projection can be provided in a simple and effective manner.

[0023] The assembly can preferably have a plurality of bayonet joints, which are preferably set to be symmetrical or evenly distributed. Thus, the effect of the connection by the bayonet joint can be correspondingly enhanced, and the connection can be provided particularly safely in general. Thus, the load of the connection can also be evenly distributed on the corresponding bayonet joint. Then, the assembly can have a corresponding blocking element for at least one, a plurality of or all bayonet joints. Then, the corresponding blocking element can be positioned in a blocking position in at least one, a plurality of or all blocking portions.

[0024] The component preferably has a polygonal and particularly preferably a quadrangular basic shape or contour, viewed in the direction of introduction. Alternatively, it is conceivable that the component has a circular and preferably annular basic shape or contour, viewed in the direction of introduction. The component can have essentially any basic shape or contour, viewed in the direction of introduction. The two aforementioned (polygonal and circular) are generally the most common and most aesthetically pleasing basic shapes or contours of the respective component.

[0025] The component can preferably have at least one bayonet fitting on each of two opposing sides. This makes it possible to achieve a uniform distribution of the connection effect, in particular for polygonal components, but also for components of other shapes, such as circular components. Thus, for polygonal components, the relative bayonet fittings can preferably be brought into the locking position by a translational relative movement between the component body and the fastening body. Thus, for circular components, the relative bayonet fittings can preferably be brought into the locking position by a rotational relative movement between the component body and the fastening body.

[0026] The component can preferably have a plurality of bayonet joints along a circle and particularly preferably be arranged evenly distributed on this circle. Such a distribution is particularly advantageous for circular or annular components in which the bayonet joint is closed by a relative rotational movement of the component body and the fastening body about a generally central rotational axis.

[0027] The fastening body preferably has a mounting structure to fasten the component body connected thereto by a bayonet joint at the mounting surface. In this regard, a simple but effective fastening method for fastening the fastening body to the mounting surface can be provided. In the simplest design, the mounting structure can be a through hole through which fasteners such as screws can be passed to fasten the fastening body. In addition, other fastening structures such as threads, latch structures, etc. can also be envisaged.

[0028] According to a particularly preferred design, the component can be a lamp, wherein in this case, the component body preferably has or is a lamp housing. For example, the lamp can be a built-in lamp, a surface-mounted lamp or a pendant lamp.

[0029] The lamp housing can preferably have an illuminating device, in particular an illuminating device for emitting light from the lamp or being illuminated by the lamp. The illuminating device can then preferably have an LED or an LED module. Thus, the lamp can be provided as a corresponding component in a simple manner.

[0030] The lamp housing preferably accommodates at least a part of the lamp electrical system and / or the lamp electronics for operating the lamp, ie at least a part of the lamp operating element. As a result, a corresponding lamp can be provided in an efficient manner.

[0031] Basically, it is also conceivable that the component can also be any other possible, preferably electrically operated component, such as a sensor, a camera, a loudspeaker, etc. The component body can then preferably have or be a corresponding component housing. At least a part of the component operating elements (for example at least a part of the component electrical system and / or the component electronics) can then preferably be accommodated in such a component housing in order to operate the component.

[0032] Furthermore, the fastening body may also support or accommodate at least a portion of component operating elements (eg component electrical system and / or component electronics) or luminaire operating elements (eg luminaire electrical system and / or luminaire electronics) in order to operate the luminaire.

[0033] Other designs and advantages of the present invention are described below with reference to the accompanying drawings.

[0046] Fig.13 Shows Fig.12 A perspective view of the assembly is shown, with the component body being partially transparent, for illustration during a second assembly step.

[0047] The figures show two embodiments of an assembly 1 according to the invention. The assembly 1 has a component body 2 and a fastening body 3 for fastening the component body 2.

[0048] The component can be any type of component. The component is preferably an electrically operated component. For example, according to a preferred design, the component 1 can be a lamp, as shown in the illustrated embodiment. Then the component body 2 can preferably have or be a lamp housing, especially as Figure 1 and Figure 2 As shown. The lamp housing 2 may preferably have a lighting device. The lighting device may preferably have an LED or an LED module. In addition, as Figure 3 As shown by way of example, the lamp housing 2 can accommodate a part of lamp operating elements, such as a lamp electrical system and / or a lamp electronic device for operating the lamp 1 , such as corresponding cables or a lamp driver.

[0049] As especially Figures 2 to 12 As mentioned above, the component body 2 can be connected to the fastening body 3 via the bayonet joint 4 of the assembly 1 .

[0050] The fastening body 3 may preferably have a mounting structure 30 so as to fasten the component body 2 connected to the fastening body 3 via the bayonet joint 4 on, for example, Figure 1 and Fig.11 At the mounting surface M schematically shown in FIG.

[0051] The component 1 can have at least one bayonet connection 4 on each of two opposite sides. This is particularly advantageous for a polygonal component 1, ie, for example, a square or rectangular component.

[0052] The component 1 can have a plurality of bayonet fittings 4 along a circle and preferably be arranged evenly distributed on the circle, as is the case in the illustrated embodiment. In the illustrated embodiment, three bayonet fittings 4 evenly distributed on the circle or circumference are provided. This is particularly advantageous for a circular component 1, as shown in the embodiment.

[0053] Overall, the component 1 can thus have one or more bayonet fittings 4 , wherein a plurality of bayonet fittings 4 are preferably arranged symmetrically or evenly distributed.

[0054] The bayonet connector 4 has a bayonet projection 5, here for example on the component body side. Figure 3 , Fig.11 and Fig.13 As can be seen by way of example, the bayonet protrusion 5 has a polygonal or square cross section when viewed from its protruding direction. Other cross-sectional shapes of the bayonet protrusion 5 are also conceivable in principle, for example, a circular cross section when viewed from its protruding direction. The bayonet protrusion 5 can preferably be configured as a pin or block.

[0055] If from 11A to Fig.11 As can be seen by way of example in step D, the bayonet connection 4 also preferably has a bayonet groove 6 (here for example on the fastening body side), in which and along which the bayonet projection 5 can be guided.

[0056] According to a preferred design, as also shown in the embodiment, the component body 2 may have a bayonet protrusion 5 , and the fastening body 3 may have a bayonet groove 6 .

[0057] like Figure 5 and Fig.13 As indicated by way of example in FIG. 1 , the bayonet recess 6 has an insertion section 60 , through which the bayonet projection can be introduced in the insertion direction E into the bayonet recess 6 .

[0058] In addition, the bayonet slot 6 also has a functional portion 61, which extends laterally away from the introduction portion 60 relative to the introduction direction E and leads at its distal end to a locking portion 62 for locking the bayonet protrusion 5, in which the bayonet protrusion 5 can be locked in the locking position (see Figure 1 and Fig.11 D) in.

[0059] As especially Figures 2 to 5 and Figures 11 to 13 As shown, the functional portion 61 tapers toward the locking portion 62 .

[0060] The functional part 61 preferably has an activation slope 65, which points to the introduction direction E and is inclined toward the locking part 62 in the introduction direction E. When the bayonet protrusion 5 is introduced into the functional part 61 toward the locking part 62, it preferably contacts the bayonet protrusion 5 so as to lock the bayonet protrusion in the locking position accordingly.

[0061] The component body 2 and the fastening body 3 preferably each have contact surfaces 21, 31 facing each other relative to the introduction direction E. The bayonet connector 4 is designed here so that the contact surfaces 21, 31 are in the locking position (see Fig.11 D) pressed against each other; this is preferably achieved by supporting the bayonet projection 5 relative to the locking portion 62 or the activation ramp 65.

[0062] In a preferred but not illustrated embodiment, the component 1 can have a seal which is preferably arranged or pressed in a circumferentially closed manner between the two contact surfaces 21 , 31 in order to produce a seal of the component 1 between the two contact surfaces in the locked position.

[0063] As especially Figure 1 and Fig.11 As shown in FIG. 2D , the assembly 1 may preferably be configured such that the bayonet slot 6 is completely covered in the locked position, preferably by the component body 2 .

[0064] Also like Figure 1 and Fig.11 As shown in FIG. 4 , the component body 2 can at least partially (as shown here) or completely accommodate the fastening body 3 in the locked position.

[0065] In addition, the bayonet slot 6 also has a blocking portion 63, which connects the functional portion 61 and the introduction portion 60. The blocking portion 63 can be arranged downstream of the introduction portion 60 in the introduction direction E, or, as shown in the illustrated embodiment, can be laterally branched from the introduction portion 60 so as to move into the functional portion 61 (see, for example, Figure 2 , Figure 3 and Fig.12 In the embodiment shown here, the blocking portion 63 preferably branches from the distal end of the introduction portion 60 relative to the introduction direction E. The blocking portion 63 may preferably branch from an end of the introduction portion 60 opposite to the introduction opening 66 for allowing the bayonet protrusion 5 to enter (introduce) the bayonet groove 6.

[0066] Furthermore, the bayonet slot 6 has a pocket 64 extending between the blocking portion 63 and the locking portion 62 and away from the functional portion 61 in a direction opposite to the introduction direction E, in which the bayonet protrusion 5 can be at least partially or completely accommodated in the retaining position.

[0067] The component 1 also has a blocking element 7 which can optionally be positioned in a blocking position in the blocking section 63 for blocking a passage 67 for the bayonet projection 5 in the bayonet slot 6 between the introduction section 60 and the functional section 61 .

[0068] like Figure 6 , Fig. 9 , Fig.11 A to Fig.11 C. Fig.12 and Fig.13 As shown, the assembly 1 is configured here so that the blocking portion 63 is at least partially exposed in the holding position so as to position the blocking element 7 in the blocking portion 63. Therefore, introducing the bayonet protrusion 5 into the pocket 64 causes the component body 2 and the fastening body 3 to be relatively offset in a direction opposite to the introduction direction E, so that the blocking portion 63 is correspondingly exposed in the holding position so as to position the blocking element 7.

[0069] In order to position the blocking element 7 in the blocking position in the blocking section 63 , a blocking element 7 , for example, but preferably a detachable blocking element, can be provided or mounted.

[0070] The blocking element 7 can also be provided (for example on the fastening body 3) for being able to be optionally in a blocking position (see Figures 6 to 8 , Fig.11 C. Fig.11 D. Fig.12and Fig.13 ) and release position (see Figures 2 to 5 , Fig. 9 , Fig.10 , Fig.11 A and Fig.11 B) at least in the holding position (but preferably also in the disassembled state of the assembly 1; for example Figure 2 and Figure 3 As shown), in the release position, the blocking element 7 releases the channel 67 for the bayonet projection 5 in the bayonet groove 6 between the introduction portion 60 and the functional portion 61.

[0071] The blocking element 7 can, for example, have a screw 70 (see Fig.12 and Fig.13 ) or screws (see Figures 2 to 11 ).exist Figures 2 to 11 In the embodiment shown here, the blocking element 7 or the screw 70 is designed as a threaded pin. Figure 4 , Figure 6 and Fig. 9 As exemplarily shown in the detailed figure in FIG. , the screw 70 may be constructed and arranged to be moved between the blocking position and the releasing position by turning the screw 70 .

[0072] The blocking element 7 or the screw 70 can preferably have a follower thread profile 73 (e.g. a groove, a cross recess, a hexagon socket (illustrated), a hexagon socket, etc.) so that the blocking element 7 can be screwed into a corresponding thread (here on the side of the fastening body 3) in a simple manner by means of a common tool W, or moved between a blocking position and a release position (see, for example, Figure 4 , Figure 6 and Fig. 9 Detailed drawing of the ).

[0073] according to Fig.12 and Fig.13 In the second embodiment shown here, the blocking element 7 can also have a pressure piece 71 with a movable pressure-bearing part 72. Fig.12 and Fig.13 As shown by way of example, the pressure component 72 is preferably preloaded into the blocking position by a compression spring to block the passage 67 for the bayonet projection 5 between the introduction portion 60 and the functional portion 61 in the bayonet slot 6. The pressure piece 71 is preferably constructed and arranged so that the pressure component 72 can be selectively moved from the blocking position into the release position against the preload of the compression spring. The pressure piece 71 can have an external thread and thus a screw 70 so that Fig.12 and Fig.13 In the illustrated installation position, the pressure piece 71 is provided, for example, screwed into the fastening body 3 in the region of the stop 63 or the channel 67. It is also conceivable that the pressure piece 71 is received in the assembly 1 in a force-fitting manner (for example, by self-clamping) so that Fig.12and Fig.13 In the illustrated installation position, provision is made—here for example in the region of the stop 63 or the channel 67 , for example—to be inserted or pressed into the fastening body 3 .

[0074] The component 1 preferably has a polygonal, particularly preferably quadrangular (eg square or rectangular) basic shape or contour, viewed in the direction of introduction E. Alternatively, it is also conceivable that: Figures 1 to 13 As shown in the embodiment of FIG. 1 , the component 1 has a circular, preferably annular, basic shape or contour, viewed in the direction of introduction E. In principle, the invention is not limited to any particular basic shape or contour of the component 1 .

[0075] The following describes the installation or removal method of the assembly 1 according to the present invention.

[0076] First, the component body 2 and the fastening body 3 are provided.

[0077] Then, the fastening body 3 can be optionally fastened to the mounting surface M. For this purpose, for example, a screw M1 can be screwed into the mounting surface M through the mounting structure 30 (see, for example, Figure 4 )middle.

[0078] like Figure 4 As shown in the detailed figure of , the blocking element 7 can be moved into the release position to release the passage 67 for the bayonet projection 5 between the introduction part 60 and the functional part 61 in the bayonet groove 6. For this purpose, a tool W can be used to move the blocking element 7, which is implemented as a threaded pin here; here, it is screwed into the fastening body 3.

[0079] Then, the bayonet protrusion 5 is introduced into the bayonet slot 6 in the introduction direction E through the introduction portion 60 of the bayonet slot 6 (see Figure 5 and Fig.13 In order to position the component body 2 relative to the fastening body 3 in a simple manner before merging, the two components can each have a positioning mark 22, 32, which indicates to the assembler the correct relative positioning of these components 2, 3. (See Figure 5 Arrow 1).

[0080] Therefore, if Figure 5 As shown by the arrow 2 in FIG. 1 , the bayonet protrusion 5 is introduced into the bayonet groove 6 in the introduction direction E, and is introduced from the introduction portion 60 through the now exposed channel in the blocking portion 63 into the functional portion 61. There, the bayonet protrusion 5 is introduced or hooked into the pocket portion 64 in the direction opposite to the introduction direction E, thereby reaching the holding position. Figure 6 , Fig.11 A and Fig.11 As shown in FIG. 2B , due to the resulting relative movement of the component body 2 and the fastening body 3 in the direction opposite to the introduction direction E, the blocking portion 63 is exposed in the holding position.

[0081] The blocking element 7 is then positioned in the blocking position in the blocking portion 63 for blocking the passage 67 for the bayonet projection 5 in the bayonet slot 6 between the introduction portion 60 and the functional portion 61. Figure 6 Detailed drawings and Fig.11 C shows by way of example that in order to position the blocking element 7 in the blocking position, the threaded pin 70 is moved or screwed in from the release position to the blocking position, preferably by means of a tool W.
