Abstract
A clamping ring for retaining a lid upon an enclosure such as a fibrous drum is provided which is formed entirely of polymeric material such as a high molecular weight, high density polyethylene copolymer. The assemblage includes only two parts, a channel formed split ring and a pivot arm joining the two ends of the split ring together over the rim structure of the container. One end of the ring supports an integrally formed pivot shaft receiving notch and the opposite end of the ring is configured having a receiver channel with spaced-apart sides and an outwardly disposed opening. The inwardly-facing internal surfaces of the receiver channel are slideably movable in adjacency over the side surfaces of the opposite side of the ring and a ring pivot shaft extends between the spaced-apart sides of the receiver channel. The pivot arm cooperates with the split ring and has a pivot end formed with a transversely disposed arm pivot shaft and a ring shaft receiving notch spaced therefrom. The arm pivot shaft is configured for slideable engagement with the ring receiving notch and the ring shaft receiving notch is configured for slideably receiving the ring second end pivot shaft.
