A drawer safety lock includes a counterbalanced latch plate, pivotally moveable manually between an upwardly pivoted limit position and an unlocked position, normally counterbalanced toward the limit position, and a latch plate stop, positioned with respect to the latch plate for restricting movement of the latch plate beyond the upwardly pivoted limit position, so that the safety lock requires no resilient bending or flexible spring action for its operating movement.
