<p>A coupling for attaching to an end of a tube, pipe, conduit or other round solid or hollow section is disclosed. The coupling comprises an inner body and a collar to be provided around the inner body. The inner body has an interior bore passing through at least a portion thereof to receive a tube or the like and the bore has one or more interior annular protuberances extending into the bore. When the collar is provided around the inner body it applies a circumferential compressive force to deform the inner body such that the one or more annular protuberances engage the tube or the like to seal with it.</p> |
