  • the Figure 15 shows the design of the first and second fastening elements 11, 21 in the form of receiving recesses into which corresponding projecting fastening areas 83, 84 of functional elements 8 can be fastened by inserting them.
  • the first fastening elements 11 are each designed as a recess in the first housing wall 10, the special case being shown in which the first fastening elements 11 are arranged at the transition from the first housing wall 10 to the second housing wall 20. It would also be possible to design the first fastening elements 11 at a distance from the second housing wall 20 as depressions in the first housing wall 10.
  • the second fastening elements 21 are designed as recesses in the third housing wall 23.
  • the Figure 16 illustrates the attachment of a functional element 8 in the form of a first locking element 81, which is comparable in terms of its locking arm 82 to the first locking element 81 in the embodiment of Figure 6 can be trained.
  • the first locking element 81 differs from this in the design of its first fastening area 84 and its second fastening area 83.
  • the first fastening area 84 is designed as an angled arm which extends over a part of the third housing wall 23 and has an angled end area in the second, which is designed as a receiving recess Fastening element 21 engages.
  • the second fastening region 83 is designed as an extension running essentially parallel to the second housing wall 20, which engages with an end region in the first fastening element 11 designed as a receiving recess.
  • the second fastening area 83 can be designed with a locking hook at the end.
  • the Figure 17 shows the attachment of two functional elements 8 according to the Figure 16 described embodiment in corresponding first and second fastening elements 11, 21 of the connector 1.
  • the functional elements 8 each engage behind a locking edge of the locking element 90 of the mating connector 9 with their locking arm 82.
  • corresponding recesses 92 are provided on the plug-in side on the front edge of the fastening elements 11 on the plug-in connector 1, which are aligned with the fastening elements 11.
  • the recesses 92 are penetrated by the fastening area 83 of the functional element 8.
  • at least the end edge of the housing of the mating connector 9 facing the fastening elements 11, 21 can be set back relative to the second housing wall 20 when the connector 1 and mating connector 9 are plugged in. This creates a free space between the mating connector 9 and the second housing wall 20 for the passage of the functional elements.
