Abstract
A lock plate (2) is secured to a door (1) or the like, by means of two upper and two lower securing means (4,5). A recess formed in one side edge (1b) of the door is arranged to accommodate a lock housing (10) having a lock pillar (12) which covers the recess. The lock pillar (12) is secured by an upper and a lower screw (6) which simultaneously serve as anchoring elements to lock the plate securing means against rotation. Each of the securing means comprises a screw-thread (5) provided with an opening or recess (5d) and co-operating with a screw element (4) which is non-rotatably received in a hole in the plate (2). Each of the anchoring screws (6) is passed through two screw-threaded sleeves (5) provided with recesses and located on mutually the same level. The anchoring screws (6) co-act with two sleeve parts (7,8) which partially surround said screws, of which sleeve parts one (7) is screw-threaded for engagement with the screw thread. The sleeve parts (7,8) are introduced into the spaces located between the upper side and underside respectively of the lock housing and adjacent surfaces defining the recess (1c) for the lock housing.
