ABSTRACT:
There is provided a safety sleeve and retainer of thin tubing which is of a size to provide a snug fit with the outer diameter of a pivot pin post as used with a watch band or strap. The sleeve is formed with at least a portion made with a tubular configuration and with about one-half made with a split. This split portion is expanded outwardly to form extending leaf portions. The safety sleeve is of rigid plastic or metal with a thin wall. The safety sleeve is adapted to retain the pivot pin post while the expanded leaf portions are a snugly slidable interference fit within a loop end of a strap or band. The safety sleeve is shown in two modes of construction. A preferred sleeve is made to enclose a previously provided spring pivot pin post. In the other embodiment the safety sleeve is secured to the outer portion of the pivot pin post and is used as an assembly.
