<p>A door-lock is provided with a lock-housing which accommodates a lock mechanism. The lock-housing comprises two connectable parts, of which at least one can be connected to a face plate which is provided with recesses for the dead bolt and latch bolt of the lock. The face plate comprises a U-shaped member which coacts with the end of the lock-housing facing the face plate to stiffen the lock-housing and form a combined unit which presents high resistance to forcing. The face plate and the member form a separate element which is removably connectable to the lock-housing. The lock-housing may either have a recess for receiving the member, said recess engaging around the two lock-housing parts, or, alternatively, the end of the lock-housing facing the face plate may be open; in which case the member enters the lock-housing through said opening and the two lock-housing parts engaging around the member.</p> |
