ABSTRACT:
A removable latch for use with a trigger actuated pump sprayer renders the sprayer child-resistant as the latch, of a one-piece plastic molded construction, is braced between a trigger actuator and an opposing portion of the pump body. The latch has an integrally molded spring biased clamp which engages the tongue of the trigger actuator provided for transmitting the manual pull force applied to the trigger to the pump piston. The latch has a spring-biased clamp engaging the tongue for removably securing the latch in place.
