<p>PCT No. PCT/SE97/01820 Sec. 371 Date Apr. 22, 1999 Sec. 102(e) Date Apr. 22, 1999 PCT Filed Oct. 30, 1997 PCT Pub. No. WO98/19031 PCT Pub. Date May 7, 1998The front end (7b) of the plug (7) of a cylinder lock is covered by a profiled element (5) which includes a key hole (6) whose profiled shape will only permit certain individual keys of a family of keys that can be inserted into the plug also to fit the profiled element. The profiled element includes attachment elements (5b) that have U-shaped engagement surfaces (7b') which co-act with corresponding engagement surfaces (7c) on a front part (7b) of the plug. The profiled element can be fitted to the lock in place, by turning the profiled element perpendicular to the plug axis. The profiled-element attachment elements (5b, 5b'; 7c, 7c') are inaccessible from outside the lock when the cylinder lock is fitted in place.</p> |
