A coupling for joining two pipe end sections, the coupling having a resilient liner surrounding the pipe ends and a force-developing member enveloping the liner and including a flexible, generally cylindrical, one-piece band having end sections capable of overlapping. These end sections have complementary locking means capable of stepped interlocking engagement over a predetermined distance upon application of an external force. The band also includes bridging means for maintaining an essentially continuous inner surface between the band end sections, and optionally, a barrier means may be interposed between the liner and the pipe ends. |
