The invention relates to an anchoring element for anchoring building structures on concrete or solid-brick supporting walls, preferably light-metal substructures for facades. In the case of known anchoring elements, such as expanding dowels, it is aimed to provide a cost-effective anchoring element which can be positioned with simple means and the correct anchoring of which is instantly visible to the workman. For this purpose, an anchoring element, similar to a blind rivet, which has a sleeve and a tensioning pin and which can be anchored in a bore by means of a conventional riveting device, has been provided. The head of the tensioning pin spreads out the sleeve end for anchoring. A marking on the tensioning-pin shank indicates, by virtue of its location after the positioning, the location of the tensioning-pin head and thus the correctly performed or non-performed spreading-out of the sleeve. In the case of an advantageous further development, the predetermined breaking point or, after positioning, the break-off location of the tensioning pin is used as the marking.
