In order to improve the introduction or uptake of force in a hollow section (1), in particular a tube, of long fibre reinforced plastic having an integrated force induction element (2) and to simplify its manufacture, a radial enlargement (4) is pressed into the hollow section (1) by means of a moulding body before the plastic matrix has hardened, which radial enlargement tapers into a narrow section (6) towards its free end (5), the jacket (3) which is formed in the process later enclosing an expansion element (9) with a clamping member (10) which merges into a tie rod (11), the expansion element (9) lying in a form-fitting manner against the interior of the enlargement (4,47) over the length of said enlargement.
