Abstract
Abstract A splice joins two pushing and pulling cables. Each cable has a plurality of gripping members defining a longitudinal cavity, a bendable power line housed in the cavity and elongated tensile elements enclosed and compressed by the gripping members. The adjacent ends of the tensile elements are connected by tensile element splices. Adjacent ends of the power lines are connected by a power line splice. A plurality of splice blocks are located end to end along the longitudinal axis, and enclose and compress the tensile element splices and the tensile element. The splice blocks define a longitudinally extending chamber housing the power line and the power line splice in a relatively stress free state.
