  • the receptacle 8 has two front-side slats 33 which protrude from the front side 31 of the wall 15 with a direction component parallel to the normal direction 9 and are deformed by the cap element 14 in the fixed state 25, cf. Fig. 20
  • the front slats 33 are circumferentially closed and are arranged concentrically.
  • the arms 28, in particular the first arm sections 29, are dimensioned such that in the fixed state 25 all front-side slats 33 are contacted by the cap element 14.
  • connection system 1 comprising the connection system 1 according to the invention and the device housing 19 with the device connection 3
  • the device housing 19 shown in connection with the third embodiment has no protruding wall sections, cf. Fig. 12 , which shows the device housing 19, and Fig. 18 , which shows the connected state 24 with the cable lug 4 arranged on the device housing 19. Accordingly, in the fixed state 25, the wall 15 is also not pressed against wall sections, cf. Fig. 20 .
