Abstract

A removable core lock and key device comprises a cylinder housing (10) and a core (20), which is accommodated in the cylinder housing. An adapter (30) is operatively connected to a bolt (32). The core and the adapter are provided with a connection (20d, 30d), such as a bayonet joint, that selectively prevents withdrawal of the core from the housing. Key actuated engagement elements (28, 30c) are arranged to selectively allow mutual rotation of the adapter and the core so as to disengage the connection, thereby allowing withdrawal of the core. A simple yet reliable removable core is thereby provided.
