ABSTRACT:
A cylinder lock is provided with a coupling device connectable via a locking beam to an additional lock structure. The locking device comprises a coupling sleeve slidably mounted on an end portion of the cylinder core. The coupling sleeve is formed with an elongated radial recess engaging a radially directed snap pin in the cylinder core so that the core is rotatable over the length of the radial slot without carrying the coupling sleeve. The coupling sleeve is also formed with a bore for engaging in another angular position of the cylinder core the snap pin so that the coupling sleeve is jointly rotatable with the cylinder core. The coupling sleeve has an end wall having a central cross-shaped recess for receiving in a selected position a flattened end portion of the locking beam.
