Abstract: A coupling device suitable for interconnecting two beam ends is provided, wherein the beam with the beam end has an elongate axis, where on a first beam end is arranged first interconnection units having two first parallel flange elements arranged with a mutual first distance x, wherein in each flange is designed a cut-out with a cross-section in the plane of the flange; a second beam end is arranged a second interconnection unit having a second flange, the width of the second flange across the plane of the second flange is smaller than or equal to x, and where largely perpendicular to the plane of the second flange, a connecting element protrudes on each side of the second flange, the cross-section of the connecting element in the plane of the second flange allows insertion of the connecting element into the cut-outs of the first flanges on the first beam end.
