Ss is "already known to provide a rush of two existing · fastening device with two ^openings": provided to attach members with each other, wherein a portion of the apparatus has the Porm a pin, · · in the. an expandable hollow member can be inserted. These known fastening devices have the disadvantage that the two ropes can be separated before assembly so that one or the other part is lost. When such a two-piece fastener is used to secure a panel to a bracket and it is then desired to remove the panel carefully, the pin must first be withdrawn from the concave member and then misplaced and / or get lost «

According to a further feature of the invention, an assembly has also been created _P which has two members provided with openings, which are held together with the aid of a fastening device defined above, - the shaft of the hollow member then extending through the openings of the two members, the Klanseh one of the links rests against an outer surface, the 'pin extends through the socket of the hollow link. **' and the free linden of this shaft is widened outward through the pin so that the two links counter the flange of the hollow link is pressed on and held together in such a way that · ', ·

According to a further feature of the invention, an assembly has been created which has two members which, with the aid of a fastening device, as defined above _? are held together, but one of the links has an opening and the other link has a bore «The Sbhaft of the hollow member extends into the
