Abstract
A lock housing having a flange; a hollow body for receiving a lock, the body being connected to the flange at one end, having an external surface and being insertable in a hole in a wall; and a spring for mounting the housing in the hole, the spring occupying a range of positions between a compressed position and a non-compressed position, the compressed position occurring when the spring is substantially parallel to the external surface and the non-compressed position occurring when the spring is at rest, the spring occupying the compressed position during insertion of the hollow body into the hole and occupying a position other than the compressed position when fully inserted to bias the flange against the wall.
