To provide a void pipe fixing implement for securing an accurate position by preventing the void pipe for piping in a concrete structure from falling down or flowing due to flow pressure during the placing of concrete.

In the void pipe fixing implement made of a resin, a foundation cylinder 3 fitted into the circle diameter of the void pipe 5 is installed as the basis for the center of a circular base 1, and the base 1 outside the outer diameter of the void pipe 5 is formed with a fixing hole for fixation to a form by a nail. The fixing implement also enables the fixation by an adhesive without using the nail. The base 1 is fixed to the form, and the void pipe 5 is fitted for fixation into the foundation cylinder 3.
