A coupling adapted to be assembled over a tubular fluid conducting member, either to connect to a section thereof or to repair a leak therein, and comprised of a body providing a protective enclosure, a sleeve positioned to the body, and a plastic seal confined by the body and/or sleeve and forceably engaged thereby to flow directly into engagement with the said member. The body and sleeve are each an assembly of laterally interlocked longitudinally split segments adapted to be assembled and disassembled laterally over said member and seal. The seal is a longitudinally split ring of plastic material adapted to flow into encompassing embracement over said member. The sleeve has two forms, one an interlocked assembly and the other a laterally separable assembly, when in working positioning over the tubular fluid conducting member. A feature of the coupling is the capability of lateral assembly and disassembly, eliminating the passing of long lengths of tubular members through a coupling and/or eliminating the requirement of disassembly of tubular member installations in order to refit or to repair leakage therein.
