摘要

1. Arrangement for releasing without destroying a normally unreleasable snap connection between two housing parts (1 and 5) put together, wherein at one housing part (1) there are arranged essentially detached snapping hooks (27) connected thereto of which each is shaped as an arm (3) elastic transverse to the direction in which the two housing parts (1 and 2) are snapped together and bearing at the free end of its arm (3) a catch (4), the catches (4) having undercuts (6) with counteropenings as parts of the outside wall of the other housing part (5) which overlap the snapping hooks (2), and having in the housing part (1) bearing the snapping hooks (2) releasing openings (12) accessible from outside in the composing direction of the two housing parts, characterized in that each snapping hook (2) is of such shape and arrangement that between the overlapping housing part (5) preferably forming the peripheral wall of the housing and deriving from the releasing opening (12) and the hook (2) there is an opening (11) of wedge shape of narrowing form in the direction of the latch (4), and in that there is a wedge (13) adapted to the opening (11) and to be inserted into the releasing opening (12), and in that in one of the two housing parts (1 and 5) there is a stop (20, 21 or 23) limiting the movement of the wedge (13) in the opening (11).
