A lock mechanism includes a lock case and a sliding bolt which is operated by a pair of link members which are mounted within the lock case. The sliding bolt has a hollow portion and carries a pair of pivotally mounted dead latches. When the sliding bolt is fully extended from the lock case, the dead latches swing out to engage a door jamb. When the sliding bolt is retracted into the lock case, the dead latches pivot into the hollow portion of the sliding bolt.
