ABSTRACT:
The nodal point connection has a nodal body (10) having bearing grooves (11-13) and coupling parts (18) which are insertable into the bearing grooves in a positive-locking manner, and spreading springs (17.1-17.4) which are arranged between the nodal body disks (10.1-10.4) defining the individual bearing grooves (11-13). The spreading springs (17.1-17.4) press the nodal body disks (10.1-10.4) apart when the screw connection (15/16) holding together the nodal body disks is loosened. The bearing grooves (11-13) provided with narrowed openings (11.1, 12.1, 13.1) are accordingly widened so that the coupling heads (18) of the coupling parts can be inserted into the bearing grooves. The coupling heads advisably have a length which is greater than the greatest cross-sectional diameter of the coupling head (18) whose cross section is adapted to the cross section of the bearing grooves (11-13).
