In the embodiment of FIG. 8 is for engagement with each locking pin 41 only one holding member available. At the free end it has a widening which further engages around the locking pin 41. The locking pin 63 is elongated in the axial direction and is closer to the other pin 62 than in the embodiment according to Fig. 1 to 7 · In this embodiment, the locking pin 63 engages directly on the locking pin 41, to hold the retaining member 21 in engagement therewith. The operation of this embodiment is the same as explained above with reference to FIGS. 1 to 7.

The connector can also be modified in other ways. Since, for example, the holding effect of the Locking members 51 to 53 is not absolutely necessary, these can also be omitted. Connectors in such a design also work satisfactorily, however, they tend to rattle and the locking sleeve is not as secure in the release and locking position held. Instead of the latching members, a certain latching can be achieved through a corresponding change the profile of the cooperating with the locking pin Run-on surfaces may be provided on the heads of the holding members.
