Abstract
A D-ring of metal wire is specially shaped to accept and retain a special grommet of a hard, wear-resistant polymeric material. The D-ring has a base leg, a pair of side legs joined to opposite ends of the base leg and converging toward each other from junctures with the base leg, and a substantially arcuate head joined to the side legs at junctures forming a neck opening that is constricted relative to a head opening defined within the head. The grommet is received within the head opening and neck opening of the D-ring and has a hole adapted to receive a hook and a peripheral groove that is in captured engagement with the head of the D-ring and with the junctures of the head and the leg portions. Portions of the groove located at the neck opening of the D-ring are deepened relative to adjacent portions of the groove within the head opening so as to retain the grommet while enabling the grommet to be pressed endwise through the neck opening and into the head opening of the D-ring.
