Abstract

The present invention relates to a plastic dowel for the fastening of a rail on a solid substrate. The plastic dowel includes an opening, an interior, a shank section, and a holding section, which provides at least one circumferential projection around its circumference. The at least one projection protrudes in a radial direction whereby the upper flank of the projection of the holding section assigned to the dowel opening is aligned at an angle of 90°±3° in relation to a longitudinal axis of the plastic dowel.
