Abstract:
1. A dowel, to be inserted in a hole in a wall, comprising: a head to remain outside the hole, said head capable of receiving a clamp therethrough and absorbing a force to insert the dowel into the hole; and a body to remain inside the hole, said body including a central core from which emerges in an orthogonal direction a series of annular retention tabs having a slightly larger diameter than the hole and at least one annular centering projection located at an end of the central core opposite the head, said annular centering projection having a diameter that coincides with that of the hole and is intended to direct the dowel into the hole, said annular retention tabs having radial notches, wherein each of said annular retention tabs forms a pair with a similar annular abutment tab which is located, with respect to the annular retention tab with which it forms a pair, in a position nearest the head, said annular abutment tab having a diameter that is smaller than that of said annular retention tab and equal to that of the hole, and wherein differences in diameters and a distance between each annular retention tab and the annular abutment tab with which it forms a pair are such that said annular retention tab can flex and rest on said annular abutment tab and on a wall of the hole.
