ABSTRACT:
For the joining of two construction parts (1, 7) which are, for example, a cross piece consisting of a profiled tube and a chair leg consisting of wood, the profiled tube has at the joining ends a non-round cross section and is slotted lengthwise at the end. The end is thrust into a fitted opening (8) in the part (7). In the slotted end of the tubular part (1) are two clamping pieces (10), which are rounded at the outer side (11) according to the form of the tubular part and have on the inner sides (12) facing each other, a wedge surface. Between these wedge surfaces a tension wedge (14) is tightened by means of a screw (16) extending outward between the clamping pieces, so that by means of the clamping pieces pressed against the slotted end of the tubular part, the tubular part (1) is clamped fast into the opening (8) of the part (7).
