ABSTRACT:
A coupling for joining a pair of conduits, one of the conduits having a flared end and the other of the conduits having a circumferential flange with a surface conforming generally for mating with the flared end of the one of the conduits. The coupling comprises a first annular ring positioned about the one of the conduits and having an inner diameter less than an outer diameter of the flared end and a radially inner surface adapted for engaging an outer surface of the flared end. A second annular ring is positioned about the other of the conduits and has an inner diameter less than an outer diameter of the circumferential flange and has a surface adapted for engaging a surface of the flange. A split ring circumscribes the first and second rings and has a radially inner, generally V-shaped groove for simultaneously overlapping both the first and second rings. The split ring has first and second circumferentially spaced ends joined by a bolt for drawing the split ring tightly about the first and second rings so that the first and second rings are urged toward each other by opposing sides of the V-shaped groove for coupling the pair of conduits.
