ABSTRACT OF THE DISCLOSURE Arrangement for frames and the like which are composed of distance elements, for example in the form of tubular struts and holding devices which keep these together in the form of coupling nodes 1, each of which comprises an initial inner portion 7 which is arranged to be clamped in a cavity in one of the elements 7 and the second outer portion 6 which is arranged to hold a second element by clamping firmly around this by means of outer contact surfaces 16. The coupling nodes 1 consist of two components 2,2 which are located on either side of a centre plane and furthermore there are for example screw devices for displacing these components in relation to each other. By this means the said clamping can be obtained during which the contact surfaces 16 move towards each other. On either side the cavity in the first-mentioned element exhibits surfaces which face away from each other. The first portion 7 of the sections has contact surfaces 21 on the same side of the centre plane as the said contact surfaces 16. When the sections are displaced and during movement of the first-mentioned contact surfaces 16 towards each other, the contact surfaces 21 of the first inner section 7 are also moved towards each other and thereby make contact with the contact surfaces in the cavity.
