ABSTRACT:
An expansible coupling for sealingly joining the ends of a pair of fluid flow passages or ducts such as exhaust gas ducts, includes an inverted V-shaped rim attached to each duct adjacent to its open end. A pair of elongate, segmented clamping members having a longitudinal, V-shaped channel therein cooperatively mate with the rim, and a flexible non-metallic seal member has the marginal edge portions thereof retained between the rim and the clamping member. A plurality of adjustable fasteners having pivotal arms for quick release are positioned regularly about each duct end and urge the rim and clamping members together to form an airtight and flexible joint between the two duct ends.
