In combination with a door hinged at one edge within a door jamb with a latch assembly mounted upon a closing edge and a strike on the jamb in registry with the latch assembly which comprises a latch within a housing pivotally mounted upon the door upon a first axis and projecting from the housing and having a lock position receiving the strike and normally biased towards an unlocked position, the strike on closing the door rotating the latch to its locking position, there being a locking aperture upon the latch. A yoke, normally biased towards a locking position and rotatable to an unlocked position is pivotally mounted upon the housing upon a second axis and mounts a latch pin adapted for interlocking registry with the lock aperture when the latch is in locking position. A spring biased reciprocal latch bar has an actuator which is adapted on retraction to retract the yoke to an unlocked position, the latch being free to move to its unlocked position on opening of the door relative to the strike. A manually operated control is mounted upon the housing and connected to the latch bar for retracting it.
