SOLUTION: At the repair time of a gas pipe, after applying the saddle 4 for a bypass pipe 16 and a saddle A for inserting gas bag to the gas pipe 8 in both sides of a repair section through an airtight seal material respectively and clamping by a clamp means 9, the bypass pipe 16 is connected to the saddle A. At this time, in the clamp means 9, when a knob 14 is turned and screwed in, a pressing metal fitting 13 is press-stuck to a rib and the pipe 8 is clamped by the saddle part 6 and a hitting metal fitting 7. While, when the knob 14 is turned in an opposite direction and the press-stick of the pressing metal fitting 13 is loosened, a connection metal fitting 11 can be turned in a clockwise direction shown on a picture and the pressing metal fitting 13 is come off from the rib 6b. As the saddle A can be installed and removed easily, a quick operation can be done, like above. |
