<p>PROBLEM TO BE SOLVED: To provide a cable connection part that can prevent waterproof performance from being deteriorated by the damage of a cable in handling up to laying and laying work even if forming is made in factories before laying. SOLUTION: A metal protection pipe 3 is covered so that a cable core connection part 2 of a cable where the outermost layer is made of cable corrosion- proof layers 1, and the end of the cable corrosion-proof layers 1 that are alienated for opposing while the cable core connection 2 is held between the cable corrosion-proof layers 1 are covered, a cylindrical metal spacer 4 that is rounded at both periphery ends is joined inside both the ends of the metal protection pipe 3, and the inner surface of the metal spacer 4 is brought into contact with the surface of the cable corrosion-proof layer 1.</p> |
