Abstract
The present invention relates to a holding device for studs having a radially projecting flange section. The holding device comprises a collet component having a clamping section and a hollow insertion section. The clamping section is formed by clamping surfaces which are provided at the free ends of a plurality of clamping arms designed to exert a radially inwardly directed clamping force for clamping the stud in place. A securing device is arranged on the insertion section and is designed in such a way that a flange section of a stud directed past the securing device is mounted in a securing position between the securing device and the clamping section. The clamping arms are of the same length and at least two of the clamping arms each have, as a securing device, a radially inwardly directed securing lug.
