Abstract
The invention relates to a rivet (2) for connecting workpieces (11, 12), in particular a blind rivet, having a sleeve (1) with a shank (5) and a widened preformed head (13) adjoining thereto, and optionally a rivet mandrel (8) with a head (9), wherein an end of the shank (5) lying opposite the preformed head (13) if necessary can be deformed to form a driven head by drawing the rivet mandrel (8) into the sleeve (1). In order that during the placement of a rivet (2) a gap (10) between the rivet (2) and workpieces (11, 12) to be connected can be closed and a highly loadable connection can be achieved, at least one indentation (3) running axially and/or at least one slot running axially are provided in the shank (5), which indentation (3) or which slot (4) during the placement of the rivet (2) causes a radial expansion of the shank (5) of the sleeve (1) towards the workpieces (11, 12).
