ABSTRACT:
A disposable, one-piece locking clip may be snapped onto a dispensing pump directly below the depressible head thereof for the purpose of blocking depression of the head so long as the clip is in place. The clip may be attached to and serve as an overlock for a permanent, selectively operable lock intended to remain with the pump indefinitely as a way of preventing accidental fluid discharge during periods of nonuse, the clip in that event serving as a means for preventing access to the permanent lock. The specific manner in which the clip is snap-fitted in place is unexposed and virtually nonaccessible so as to prevent removal of the clip or actuation of the pump without first pulling a break tab that splits the clip in half and releases the same from the pump.
