The frame has struts (22) connected by clamping nodes (1) each of which has an internal section (7) clamped in a cavity in one of the struts and an outer section (6) to grip a second element by clamping around it via outer contact surfaces (16) on the coupling node. The cavity has surfaces directed away from each other and located on either side of the central plane in the intended position of the coupling node. The first part of the section contact surface (7) is on the same side of the center plane for making contact with the contact surfaces (21) of the inner surfaces of the cavity face away from one another. These surfaces (16,21) are moved together and rest against the contact surfaces of the cavity. |
