ABSTRACT:
Two free-standing tubular columns (1, 2) having slots (3), parallel to the longitudinal axis of the tube, for locating extension arms or supporting arrangements are connected to one another according to the modular construction principle by means of a cross connection (4). The cross connection (4) of two connecting tubes (5, 6) contain, at their ends, one attachment housing (8) each, in which, on the one hand, these two connecting tubes (5, 6) are held and, on the other hand, a clamping bracket (13) having catch projections (16) is accommodated. The catch projections (16) are intended for engaging into the slots (3) of the tubular columns (1, 2). Each attachment housing (8) is provided at the front face with a surface contour complementary to the outer contour of the colunm, and a clamping screw (17) preloading the clamping bracket (13) against the attachment housing brings about an applied-pressure connection between the attachment housings (8) and the tubular columns (1, 2).
