  • the angle of rotation depends on the positioning of the locking cams 25 in relation to the lugs 5. Since the angular difference in the present case is 90 degrees, the handle ring 26 makes a corresponding rotational movement by the operator 90 degrees Degree. After completion of this rotational movement are thus the locking cam 25 in front of the introduction channels 8 and, since these correspond in shape and design to the channel shapes of the introduction channels 8, the locking cam 25 are pressed by the relaxing spring 27 in the insertion channels 8, whereby a lock and at the same time Anti-rotation is given (see Fig. 14 ).
  • the cams 5, which look like from the FIG. 14 can be seen, offset by 90 degrees to the insertion channels 8, ensure that the plug 2 'can not be pulled out of the socket 1' in the axial direction.
  • twisting motion in the form of 90 degrees is called only for example. In practice, other values are possible here as well.
  • connection system according to the invention can be easily introduced into existing walls, for example in walls of a trunk in a vehicle at any point. If a sufficient wall thickness of the wall 34 is present or if it is correspondingly reinforced, it is also possible to attach heavy loads or secure heavy loads with the connection system according to the invention to the holding eye 30 of the plug 2 '.
  • FIGS. 1 to 10 Another advantage over the embodiment according to the FIGS. 1 to 10 it is also the fact that by the rotation of the rotary member 28 relative to the handle ring 26 connected to the rotary member 28 retaining eye 30 can remain unchanged in a rotation of the plug 2 'when inserted into the socket 1' to its locking in position. This means that it is not mitverfiltert and parts located thereon or provided in place of the holding lug 30 consumers remain in their original position.
  • the embodiment of the FIGS. 1 to 10 will be in the Fig. 6 illustrated consumer 22 mittwreht when making the bayonet connection, which could lead to problems in the event of the need for a correct position arrangement of the consumer 22, the holding lug 30 or another connected to the holding lug 30 or with the plug 2 'self-connected part.
  • Cam carrier 23 and handle ring 26 can be rigidly connected to each other in any way. This can be done for example by a screw or gluing.
