Abstract: The resin anchor comprises an apertured tubular envelope designed to be compressed by a traction element, characterized in that it includes, on the inside of the envelope, a resin component and a hardener component that are intended to be mixed together and to cure under the action of the compression of the envelope (1), in order to fasten the anchor, at least one of the two components being sacheted, the mix formed from the two components being expelled out of the envelope via its apertures, during its compression. The traction element may be a screw that cooperates with the end element of the bushing CD forming a nut. The anchor is fastened both mechanically and chemically, for either solid material or hollow material.
