To provide a drain pipe fixture which can easily secure a draining grade of natural drainage.

The drain pipe fixture 5 functions to fix a drain pipe 401 which has flexibility, is for use for natural drainage, and arranged on a rear side of a wall 3 to be drawn via a penetration hole 3a formed in the wall 3, to the penetration hole 3a. The drain pipe fixture 5 is formed of a blocking member 8 having a through-hole 8b formed therein, for leading the drain pipe 401 and blocking the penetration hole 3a, and a limiting member L. When the drain pipe 401 is pulled in one direction P along the drain pipe 401 toward a front side of the wall 3 so as to be strained on the rear side of the wall 3, the limiting member L allows the drain pipe 401 to move in the one direction P but inhibits the drain pipe 401 from returning after the movement.
