A door latch without outwardly projecting knobs or the like is comprised of a normally extended bolt which is longitudinally retractable by an actuator having generally disc-like inner and outer housings mountable on the door with their outer surfaces essentially faired with those of the door. The inner and outer actuator housings include outwardly opening recesses into which a hand is insertable to engage longitudinally movable vertical pusher bars positioned therein for retractively moving the bolt. A pivotal lock member rotatively supported from the inner housing is provided to lock the latch from the inside of the door; but can be moved to unlock the latch from both sides thereof.
