Two of the hollow profile connections (6,8) are closed at one end by covers (10,12) and a center sector (14) of the nodal junction (5) lies between the closed connections (8) and with 1.5 to 2 times their wall thickness. This center sector is designed as a hollow tube piece coupled non-rotatably to the closed connections via two identical connecting elements (15,16) and thus prevented from axial release. The nodal junction element forms an S-shape with connections (8) ends or again forms an X-shape in which two branched end parts are linked via the center sector (14). In this, each end part comprises two hollow connections (6-9), with one connection at each end covered off (10,12). The nodal junction element is hydraulically formed for preference.
