Abstract
A handle for a valve stem having a polygon shaped cross section has a transverse hole for receiving the polygon cross section portion of the stem. A second hole having an axis perpendicular to the transverse hole intersects a portion of the transverse hole which is adapted to receive one of the corners of the polygon shaped valve stem. A removable pin is thereafter forced into the second hole to deform a portion of the valve stem and retain the handle on the stem.
