A clamp ring includes an elongated band formed into the shape of an open generally circular ring with opposing first and second ends. A cam lever is pivotally connected to a first end of the band and a link has one end pivotally connected to the cam lever. The opposite end of the link is connected to the second end of the band such that pivotal movement of the cam lever will selectively draw the ends of the band towards one another to secure the ring in position on a container. A removable handle is provided to engage and pivot the cam lever 20 and includes a polygonal pin for engagement with a corresponding socket on the cam lever.
