Abstract

Abstract A manually operable pin for a wrist watch band comprising a pair of hollow, tubular members in telescopic relation. The members have extending pintles at their outer ends for engaging the watch bail openings. The inner member has a longitudinal slot spaced from the inner end. The outer member has a manually engageable tab extending upwardly adjacent its inner end. Spaced from the tab, a portion of the body extends inwardly into the slot on the inner member to permit relative telescopic movement within the limits of the slot. A coil spring is mounted within the members to normally bias the members in extended position. To lock the pin to a watch bail after it has been inserted in the end of a watch band, the pintle on the inner member is placed into one bail opening. The tab is manually moved against the action of the spring to shorten the pivot pin and allow the pintle on the outer member to be inserted in the other watch bail opening. The pivot pin is removable in the same manner, by manually engaging the tab and telescoping the members to shorten and remove the pin. No tool is necessary to insert or remove the pivot pin.
