The system comprises coupling elements (4) for the releasable connection of the profiled tubes (1) to the node elements (2). The pin-shaped and bore-shaped coupling elements are fitted into one another and are connected force-fit at both ends of a profiled tube to a node element by a turning movement. The node elements and the coupling elements consist of rigid material and one of the elements is narrowed or expandable corresponding to its diameter. |
