Abstract
A plastic locking ring for locking a lid on a drum includes an elongated strap of extruded plastic polymeric material. The strap has an H-shaped cross section defined by a rib and four flanges extending from either edge of the rib. A fastener extends from one end of the rib and is secured to the other end to form a circular ring locked about the lid and drum. Lips extend downwardly from the inner flanges of the circular ring to stabilize the ring on the lid and drum. The plastic locking ring is formed by extruding polymeric material through an extrusion die to form a strap, curing the plastic polymer, cutting the plastic strap into predetermined lengths, and fixing a fastener element to each end of each strap length.
