Abstract
A handle assembly includes an open-ended sleeve connectable to a valve stem by a screw inserted and removed through the open end. A removable cap has four cross openings which align with four cross openings in the sleeve. Two cross members are placed in the cross openings and interfitted inside the sleeve. In one embodiment, the internal connection is provided in part by a hole in one of the cross members. In a preferred embodiment, the cross members have contacting surfaces for engaging the sleeve and the cap. The handle assembly is adjustable for use with a variety of sleeves.
