ABSTRACT:
A circular pipe coupling for coupling aligned pipe ends is formed of arcuate segments arranged end to end. Each segment has outwardly extending lugs formed on its opposite ends, with the lugs on the adjacent segment ends being interconnected. One of each pair of interconnected lugs is formed with an integral hook, with a corresponding opening for receiving the hook formed on the opposite lug and providing an axle upon which the hook is engaged to form a hinge connection, except that one of the pairs of lugs is connected together by a manually releasable mechanical fastener, such as a bolt. One of the segments may be manually positioned upon the adjacent pipe ends to be coupled, with one or more segments freely dangling downwardly therefrom under the force of gravity, which sections may be manually pivotal upwardly for encircling the pipes and for applying the releasable mechanical fastener.
