Abstract

To secure a cylinder core (7) of a locking cylinder (3) against being pulled out of the locking-cylinder housing (5) by force, there are proposed retaining pins (41) which are seated in bores (43) of the cylinder core (7) and which are prestressed by springs (45) into, for example, sickle-shaped grooves (47) of the receiving bore (13) of the locking-cylinder housing (5). The retaining pins (41) each have, at their end engaging into the groove (47), a knife-edge cone (51) which widens towards the groove (47) and which, during an attempt to pull the cylinder core (7) forcibly out of the locking-cylinder housing (5), prevents the retaining pin (41) from sliding back into its bore (42). Retaining pins (41) of the foregoing type require only a comparatively small amount of space in the cylinder core (7) which is consequently not needlessly weakened. Furthermore, sufficient constructional space for accommodating additional blocking pins (33) or the like remains in the cylinder core (7). <IMAGE>
