PCT No. PCT/SE81/00333 Sec. 371 Date Jun. 22, 1982 Sec. 102(e) Date Jun. 22, 1982 PCT Filed Nov. 11, 1981 PCT Pub. No. WO82/01733 PCT Pub. Date May 27, 1982.In an attachment fitting for cylinder locks (3, 3') the heads (4a) of a plurality of screws (4) are seated in a widened hole portion (5a) in the lock. A plugging or latching element (6) is arranged to co-act with a sealing pin (7) in a manner such that when the plug (3a) of the cylinder lock (3) is turned to a given position by means of a key, the sealing pin (7) moves inwardly in a peripheral hole (9) arranged in the plug, against the action of a spring (10). This enables the plugging or latching element (6) to be removed. Because of the presence of the plugging or latching element (6), however, the screw heads (4a) cannot be reached in order to loosen the screws by persons not having the correct key to the cylinder lock. The screws connect the cylinder lock (3) to a further cylinder lock (3') on the other side of the door.
