  • the engagement of the pins 333 in the recess 213 also provides a rotation lock between the housing parts 2, 3, so that the housing parts 2, 3 are fixed to one another in their rotational position. Because the ring 50 is axially offset from the pin 333 on the collar 330, the pin 333 lies in the recesses 213, while the ring 50 engages behind the locking lip 212, so that a rotationally secured positive connection between the housing parts 2, 3 is made.
  • the collar 330 Provided on the collar 330 are four pegs 333 spaced apart from one another by 90 ° about the application direction A, which are to be brought into engagement with four recesses 213 on the inner border 210 of the opening 21.
  • the equidistant arrangement of the pins 333 and the cutouts 213 enables the housing parts 2, 3 to be connected to one another in four different rotational positions, each of which is rotated by 90 ° relative to the application direction A.
  • the rotation lock via the pins 333 and the recesses 212 can be dispensed with and replaced by a rotation lock according to one of the previously described exemplary embodiments.
  • a closure element 5 in the form of a plate-shaped spring element 51 is arranged on the second housing part 3, which along an adjustment direction V is adjustable transversely to the direction of attachment A on the second housing part 3.

  • the second housing part 3 is attached to a collar 24 on the mounting surface 200 of the first housing part 2 with an opening 33 formed in the mounting surface 300.
  • the spring element 51 is located in the in Figure 14E shown, only partially inserted into the housing body 30, so that the ends of the arms 510, 511 protrude approximately centrally (viewed along the adjustment direction V) into the opening 33 on the side edge of the opening 33. In this position, the ends of the arms 510, 511 can be passed in the attachment direction A through cutouts 242 on an upper edge 240 of the collar 24 of the first housing part 2.

  • the locking element as a spring element is made of spring steel, for example, and the housing parts of the housing are made of metal, in particular aluminum, then it must be ensured that there is no corrosion when the locking element is attached to the assigned housing part. Such corrosion could occur in particular if the locking element is made of steel and the housing is made of aluminum.
  • the locking element can have, for example, a suitable coating, a varnish or a zinc coating which counteracts corrosion on a contact surface between the locking element and the housing part.
