Abstract
This is a retaining device for locking pistons that have retractable sliding arms. The retaining device has a first ring portion having interior, exterior, and two end surfaces with screw receiving areas. A receiving area for a holding screw extends from the interior surface to the exterior surface of the first ring portion. A second ring portion also has interior, exterior, and two end surfaces with screw receiving areas. The ring portions are assembled through use of screws to form a collar. A holding screw with a handle, sized to be threaded into the receiving area of the first ring portion, locks the retaining device onto the piston arm.
