Abstract

A holding device for holding a stud, which includes a radially projecting flange in a securing position, comprises a collet component including a hollow tubular insertion section defining an insertion axis, and a clamping section operable to exert a radially inwardly directed clamping force for clamping the stud. A securing device is arranged on the insertion section and includes a securing sleeve formed of plurality of separate securing-sleeve sections that are radially movable relative to one another. A clearance space is defined between a bottom end of the securing-sleeve sections and a top end of the clamping section, and the clearance space is operable for holding a flange of a stud in the securing position.
