ABSTRACT:
Couplers for coupling conduit in end-to-end flow communication relationship are disclosed. A coupler has at least two coupling members each having one end hingingly attachable to one end of another of the at least two coupling members, and one of each coupling members having one end configured with a first cooperating attaching component and the other of each having one end configured with a second cooperating attaching component. There may also be a pressure producing element which increases coupling forces when said first and second cooperating attaching components are attached. There may also be corrugations in the walls of one or all of the coupling members that fit within corrugations of corrugated conduit being connected. The inside diameter of the coupler is about equal to or greater than the outside diameter of the conduit being thereby coupled. In addition, a plurality of couplers and/or coupling members may be used to couple conduit with small diameters and conduit with large diameters. The larger the diameter of the conduit the more coupling members are needed to so couple the conduit.
