Abstract
A valve and handle assembly is disclosed for controlling the flow of breathing oxygen from lightweight oxygen cylinders. The valve provides a stem extending from the valve formed with a plurality of barbs which provide ramps and shoulders. The stem also provides opposed wrenching flats. A handle formed of polyvinyl chloride or the like is provided with a through bore having ramps and shoulders proportioned to mate with ramps and shoulders on the stem. The handle also provides opposed flats. The handle is sufficiently elastically deformable to allow it to be assembled on the stem by axial movement. After assembly, the shoulders on the handle engage shoulders on the stem to permanently secure the handle in position. When installed, the handle returns to a substantially unstressed condition so that crack-inducing stresses do not exist in the material forming the handle and a permanent, strong connection is provided between the handle and the stem.
