Abstract

A clamp that includes a collar having first and second ends from which first and second lugs extend. Each of the first and second lugs has a thick portion and a thin portion, and the lugs are connected by a fastener. The clamp is positioned around tubes, and the fastener is tightened to tighten the clamp around the connection. The fastener may be tightened from an open position OP, when the lugs are not touching, to a closed position CP, when the thick portions of the lugs are touching. The fastener may be tightened further to a third position, so that the thin portions of the lugs move closer to one another. The clamp may also include a hinge area in which a gasket seal may be attached to the clamp or one of the tubes.
