Abstract

An apparatus for detachably fastening an equipment housing to a profile rail, preferably a top-hat rail mounted on a wall or bottom surface, includes guide strips. At least one clamp part slides on the guide strips and engages the profile rail in a clamping position like a tong. The at least one clamp part is retained in a clamping position by spring force operating in a given direction and is displaceable into an open position counter to the given direction for loosening. At least one locking part is displaceable relative to an equipment housing and is coupled to the at least one clamp part. The at least one locking part and the at least one clamp part occupy at least two positions defining a mutual spacing. The at least one locking part blocks the at least one clamp part in one of the positions for preventing the at least one clamp part from being displaced into the open position for loosening the equipment housing from the profile rail.
