A lock for sliding doors including a first door and a second door slidable with respect to a second door. The lock is mounted on the second door and has a housing engaging the side surface of the frame of said second door. The housing has an inner wall adjacent the frame of the first door, an outer wall and an intermediate wall between the inner and outer walls. A plunger is slidable in openings in the outer, intermediate and inner walls. Spring means yieldingly urge the plunger outwardly. The opening in the outer wall has a noncircular configuration, the opening in said intermediate wall has a similar configuration but circumferentially oriented with respect to the opening in said outer wall, and the shaft has a laterally extending projection corresponding to the configuration of the openings in said inner and outer wall. The first door has an opening therein into which the plunger extends such that the plunger can be held outwardly out of locking position by moving the shaft and rotating the same so that the projection thereon moves through the opening in the intermediate wall and the opening in the outer wall and engages the outer surface of the outer wall and the lock may be engaged by rotating the shaft such that the projection thereon permits movement of the shaft under the action of the spring means through the opening in the outer wall and thereafter further rotation of the shaft permits movement of the shaft and the projection thereon through the opening in the intermediate wall so that the shaft engages the opening in the first door and is held against movement axially outwardly by engagement of the projection thereon with the inner surface of the intermediate wall.
