Underwater cable protection pipe

An underwater cable protection pipe comprising two identical longitudinal half-pipe sections interconnectable with one another by integrally formed interlocking mating connectors, said half-pipe sections when interconnected together in juxtaposition forming a longitudinal hollow pipe having a stub end and an articulatable clamping ball end shaped to clampingly receive said stub end of a like pipe to interconnect two or more of said pipes end-to-end about a submerged cable, and wherein connectors are integrally formed on opposed sides of said clamping ball end and when interconnected are disposed on a diametrical axis of said ball end permitting said half-pipe sections to pivot on said connectors, said connectors being constituted by a transverse pin projecting laterally adjacent a top end edge of said ball end of said half-pipe section and a hook connector projecting on an opposed side of said ball end, said hook connector having an arcuate jaw formation disposed in axial alignment with the longitudinal central axis of said transverse pin for receiving in friction fit a portion of said transverse pin of a mating half-pipe section and on opposed sides of said clamping ball end whereby to interconnect and align two of said half-pipe sections together.
