A gate for providing a barrier to an opening comprises a frame which is securable in the opening and a gate attached to the frame and pivotable to open and close the opening. A lock mechanism releasably secures the top and bottom of the gate to the frame and comprises a housing secured to the top of the gate, an operating handle movable vertically with respect to the housing, a latch secured to the handle for releasably engaging the top of said frame, and a locking rod fixed to the operating handle for releasably engaging the bottom of the frame. At least one coil spring is compressed between the operating handle and housing for biasing the operating handle downwardly to a position where the latch engages the top of the frame and the locking rod engages the lower frame member to lock the gate closed.
