PROBLEM TO BE SOLVED: To provide a fixing device for a hot-water supply relay pipe, by which the setting works of a mixing faucet can be facilitated including fine adjustment correctly setting the mixing faucet in parallel with a wall surface. SOLUTION: In the fixing device 4 for the hot-water supply relay pipe 5 for connecting a hot-water supply pipe to a mixing faucet on the wall surface side, a circular member 25 is connected continuously to a relay pipe body 10 towards the wall surface side while a cylindrical member 28, in which a male screw section is formed to an outer circumferential surface and which is used for fitting the circular member 25, is connected continuously to a fixing member 27 fixed onto a wall surface 1. A box nut 30 screwed to the male screw section is held previously to the circular member 25 while a metallic split ring 31, in which a diameter can be contracted, is arranged between the box nut 30 and the end section of the cylindrical member 28, and a tapered surface section contracting the diameter of the split ring 31 by clamping the box nut 30 is formed to at least one of the end section of the cylindrical member 28 or the box nut 30.
