摘要： A retainer subassembly for a master link of a chain includes a cover plate, a pair of snap rings and a strap plate. The cover plate includes a pair of stepped recesses terminating in openings adjacent the outer face of the cover plate for receiving the spaced pins of a master link. Snap rings having radially inwardly extending and axially outwardly inclined tangs are disposed in the recesses. A strap plate overlies the inside face of the cover plate. To apply the retainer subassembly to the master link, the holes through the retainer subassembly are aligned with the pins and the retainer subassembly is pushed onto the pins. Once the flanges of the snap rings pass the ends of the pins, the flanges resiliently snap into the annular grooves of the pins retaining the retainer subassembly on the master link.
