A lock for a sliding door is disclosed which comprises an elongated escutcheon having a slidable latching means. The latching means moves between an "open" and a "locked" position. The escutcheon includes means for releasably retaining the latching means in both of the positions. The latching means includes an elongated slot of a first width having at least one enlarged portion of a second width and a locking mechanism having a bolt which extends through the slot and is rotatably secured to the escutcheon. The portions of the bolt extending through the slot have an irregular periphery so that facing in one direction the thickness of the bolt is greater than the width of the portion of the slot of the first width, yet smaller than the portion of the slot of the second width. When the bolt faces in a position rotated a predetermined angular amount from the position facing in the one direction, the thickness of the bolt is less than the width of the slot of the first width. The slot is enlarged at each end thereof so that the latching means can be locked in both an "open" and "locked" position.
