Abstract
Two cable ends have their cores jointed in a conventional manner. The ends of armor wires, laid up on the cores, are laid with overlap over the core joint. A sleeve with radiused and increased external diameter ends is arranged over the overlap at the core joint. The ends of the armor wires are turned back over the ends of the sleeve such that they come to rest on the outermost surface of the sleeve and are secured thereto by strappings. The outer surface of the sleeve may be coated with an adhesive and gritted to increase the adhesion between the armor wires and the sleeve. The thus spliced armor wires may be provided with a protective winding. The armor splice is such that only a low elongation of the armor wires is possible when longitudinal force is applied to the cable, thus making it particularly suitable for an armored submarine cable including optical fibres.
