Abstract
The present invention relates to a lock (3) on the inside of a door, wherein the lock can be actuated from outside the door. The lock is connected to a locking device (14) on the outer side of the door by a coupling rod (12). In order to increase protection against burglaries, the coupling rod (12) is to pass through a channel (22) with which a channel closure jaw (28) is associated. The jaw is supported on the coupling rod (12) and is under spring-load in the direction of closure. Removal of the coupling rod during a burglary attempt results in a closure of the channel with protection of the lock from tampering by the jaw.
