The invention starts from a fastening element for attaching to a wall having a contact element having an adhesive surface (21) and a filling opening (18) via which a flowable adhesive agent can be brought between the adhesive surface (21) and the wall. Positioning elements (23a, 23b, 23c, 23d) by means of which the contact element can be positioned at the wall are arranged at the adhesive surface (21). To allow a good adhesion to the wall, it is proposed in accordance with the invention that the positioning element (23a, 23b, 23c, 23d) has a width which is variable in dependence on a spacing from the outlet opening (18). The width reduces at least sectionally as the spacing from the outlet opening (18) increases and is minimal at a maximum spacing (29) from the outlet opening (18). It is thus achieved that the adhesive surface can flow very easily around the positioning element (23a, 23b, 23c, 23d) on the introduction between the wall and the adhesive surface (21). |
