ABSTRACT:
The disclosure is of a closing ring assembly for sealing the cover of a drum type of container. The assembly comprises a split ring, the ends of which are connected by a bolt secured through a pair of bolt clips mounted on the ends of the split ring. The bolt clips comprise tubular members having flared open ends. The clips are positioned in a specific manner to receive the bolt component without interfering with rolling of the drum. In a preferred embodiment, the bolt clips include a threaded retainer member to cooperate with a threaded bolt. The assembly of the invention is advantageous in that it is more economical to manufacture, more secure in use, easier to operate and stronger than prior art closing ring assemblies.
