Abstract

In order to elongate and relax a stud, a first part which is movable only axially engages the stud, a second part is connected with the first part and a friction element is connected with at least one of the parts so that the first part has more surfaces cooperating with other elements than the second part(s). At least a holding force is applied to the friction element while an opposite active force is applied to the second part so that the second part is moved in the transverse direction and the first part is moved only axially to elongate or relax the engaged stud.
