Device for preventing a device mounting plate or other electro-installation device on a cable guidance channel from moving

摘要

The device has a holding frame (10) defining a central opening, and a clamping element (20) inserted into a frame element (12) and comprising a base body (23). The clamping element is inserted into the frame element, such that the clamping element is movable from a mounting position to a locking position along a guide (19) i.e. rail. A flange (28) lies on the frame in the mounting position, and the clamping element presses an inner bar of the frame against a form-holding profile i.e. cover holding profile, of a channel lower part for producing a frictional connection in the locking position.
