ABSTRACT:
The invention relates to a door lock, which comprises, a lock body (1) provided with a forend and including a latch bolt (3), which is removable between a retracted position and a protruding, locking position out from the lock body through an opening (2a) in the forend (2) and which is spring-loaded towards its said protruding position, and dead locking means turnable from a passive position into a dead locking position, in which they prevent removal of the latch bolt (3) from its said protruding position into its retracted position in the lock body (1). According to the invention the latch bolt (3) comprises a body of the latch bolt (3a) and a separate latch bolt member (3b). The latch bolt member (3b) is supported on the body of the latch bolt (3a) so as to be turnable substantially around a longitudinal axis (24) of the lock body and formed to narrow down in a wedge-like manner towards the outer edge thereof, said bevelled part of the latch bolt member (3b) extending, in the protruding position of the latch bolt (3), substantially out from the lock body (1).
