Abstract: A retaining device for attachment of objects to a wall surface includes a main body, a fastening arrangement, and a cover lockable to the main body that arches over the fastening arrangement. The main body has a bottom side, that faces the wall during mounting, and a top side, that faces away and includes a retaining ring. The fastening arrangement includes a fastener and a centering cap which fixes the fastener. The bottom side of the main body has a circular-ring-shaped surface, on inner and outer edges of which, in each case, one closed encircling web is provided which faces away from the bottom side. Two passage openings are provided in the circular-ring surface between the top and bottom sides. When attached, the main body is pressed onto the wall and an adhesive is injected through one of the passage openings until it emerges again at the other passage opening.

Abstract: A lightweight construction fastener or clip having a clip body and a fastening element 32. The clip body includes a first leg and a second leg, which are connected with each other by a web 45 at one end. The clip body is formed of one piece, but includes at least two volume sections 61, 62, wherein the first section 61 is formed of a first plastic and the second volume section 62 is formed of a second plastic. The properties of the first and second plastics are different from each other with respect to one or more criteria. A method for producing such a clip body includes manufacturing it in one piece in a multi-component injection molding process from at least two plastics. Further the invention includes a method for manufacturing the lightweight construction fastener or clip by placing a fastening element 32 into the injection molding tool; encapsulating the fastening element 32 and overmolding the fastening element 32 in a multi-component injection molding process.
