Anchoring device, characterized essentially by the fact that it consists of a tapping intended to be embedded in one of the surfaces to be joined, provided with a head projecting to the outside preceded by an annular throat, whose anchoring device is completed by a second body as a recessed cup in the other body to be joined, and which has an opening on its front side that consists of two sections, one wider than the head of the stopper and the other narrower, but at the same time wider than the throat of the bushing, both sections of the opening being in communication through a narrow passage which is pressurized by the throat of the bushing.
