PROBLEM TO BE SOLVED: To improve fitting property and material strength in a conduit or a water stop retainer of a cable.SOLUTION: Two divided annular flanges 5 holds divided annular elastic bodies 4a, 4b, 4c therebetween and a screw bolt 62 inserted between the divided annular flanges are screwed using box wrenches 71, 72, thereby, the annular elastic bodies are compressed and deformed. A conduit or a cable 3 is fixed to a sheath pipe 2 inside a concrete wall or an inner surface of a through hole in the concrete wall. The divided annular flanges are formed of metal or a reinforced plastic. A swollen part 40 is pressed by a sheath pipe inner surface or the inner surface of the through hole in the concrete wall and the cable to hold a gap between the sheath pipe inner surface or the inner surface of the through hole in the concrete wall and the cable in a completely water tight state.SELECTED DRAWING: Figure 1 |
