とがなくなる。In order to solve the above-mentioned problems, a fixing device according to the present invention is fitted to an outer peripheral surface of a fluid pipe so as to be able to contact a side end face of a split case body externally fitted to the fluid pipe. Combined
A ring-shaped or oval-shaped fastener formed on a tapered surface whose outer peripheral surface gradually increases in diameter toward the split case body side, and is externally fitted to a fluid pipe on a side of the fastener so as to be movable in the pipe axis direction. The inner peripheral surface is constituted by a pressing portion formed with a tapered surface that can be in close contact with the outer peripheral surface of the fastener, and a split ring having a flange that can be fastened to an end of the split case body by a fastening means. The pressing portion is fitted inside the eave portion provided at the end of the split case body. With this feature, after the fastener is brought into contact with the side end surface of the split case body and fitted to the fluid pipe, the pressing portion is fitted inside the eave portion provided at the end of the split case body, When the flange of the split ring fitted over the fluid pipe is tightened to the split case body by the fastening means, the tapered surface of the pressing portion of the split ring is pressed against the tapered surface of the fastener,
Press the fastener in the radial direction. Thus, the fastener strongly presses against the outer peripheral surface of the fluid pipe and is fixed to the split case body. When the fluid pipe tries to move, the diameter of the fastener is further reduced by the tapered surface, and the fixing force is increased. At this time, since the eaves portion receives the reaction force from the fastener applied to the pressing portion, the pressing portion of the split ring is not opened, so that the pressing force of the fastener is reduced and the fixing force is not reduced.
