A support profile (10) has axially or vertically running webs (11) which are approximately T-shaped in cross-section and form, between them, corresponding, groove-shaped receiving locations (12). Load-bearing members (13, 14) for wall and/or floor parts are releasably fastened on the support profile (10) in each case by means of a tension lock (15) which is received in a load-bearing-member chamber, preferably in the interior of the hollow load-bearing member (13, 14). The tension lock (15) contains in each case three plate-shaped retaining elements (16, 17, 18) which engage radially into three neighbouring groove-shaped receiving locations (12) between four neighbouring webs (11) of the support profile (10). The three retaining elements (16, 17, 18) can be braced, by a tightening screw (24) arranged in the transverse direction with respect to said elements, against one another and against the webs (11) of the support profile (10). By tightening the tightening screw (24), the two outer retaining elements (16, 17) are simultaneously tilted, in the manner of a set of scales, about edges (67) provided on the central retaining element (18), with the result that their rear ends are braced against the inner wall (71) of the load-bearing-member chamber receiving the tension lock (15). A secure fastening of the load-bearing members (13, 14) on the support profile (10) is thus made possible at each point along the same using simple means. <IMAGE>
