ABSTRACT:
A split coupling of clam-shell configuration applied laterally over abutted ends of confronting tube sections with bead-over-wire reinforcement engaged with opposed shoulders of separable body members, and having depressible ring and abutment seals molded into the separable body members hinged for abutment on a diametrical axially disposed plane coincidental with the axis of the body members when closed over said confronting tube sections by link and latch means, all basic structural members operating in tension and shear connections multiplied for greater strength and for uniform load distribution, said ring seals being scarfed for circumferential continuity, and there being an electrical bond between the coupling and said confronting tube sections.
