A fastening means for pre-assembly of a pin-shaped joining means in a through-hole of a structural element comprising a cylinder barrel-shaped sleeve, a plurality of first holding elements disposed at the inner side of the sleeve and projecting inwards, and a plurality of third holding elements disposed at the outer side of the sleeve and projecting outwards, and second holding elements projecting outwards from both ends of the sleeve, that project farther outwards than the third holding elements, and that are elastically deformable, such that upon insertion of the fastening means into the through-hole, they perform an evasive movement. |
