ABSTRACT:
A device for coupling the peripheral flanges of a pair of pipes comprising a pair of retaining members, each having a V-shaped groove for receiving a portion of the peripheral flanges of the pipes. The retaining members are pivotally coupled at one of their ends by a single hinge and releasably coupled at their opposite ends by an over-center latch mechanism. The over-center latch mechanism employs a compression bolt and nut to maintain a low profile. The over-center latch mechanism also has primary and secondary link members, the latter preventing the coupling from completely separating should the primary link members fail.
