PURPOSE:To facilitate water-proof treatment of cable joint, by securing a portion of a tube to the outer circumference of a tubular body then folding back one end portion of the tube and placing a slippery material at the inside. CONSTITUTION:A water-proof tubular member 11 is constructed a tubular body 12, an elastic rubber tube 13 and a slippery film member 14. The tubes 13 are arranged at the opposite ends of the tubular body 12, where one end of each tube 13 is secured to the end of the tubular body 12 while the other end is folded back to enlarge the diameter. The slippery film member 14 is placed at the inside of the folded portion of the tube 13. Water-proof treatment is carried out by unfolding the tube 13. |
