<p>A connecting element consists of a sleeve insert (3), connected to a rod, and a bolt (5), connected to a bolt (10). The bolt (5) runs through a passage of the sleeve insert (3) and a passage of a sleeve (12) being arranged between the sleeve insert (3) and a node (10), wherein a cross-section of the inner region of the sleeve (12) and central region of the bolt (5) is polygonal to form a shaped contact to transmit rotational movement of the sleeve (12) to the bolt (5). The bolt (5) is made of a single piece and its middle has a cylindrical part (7) abutting to a head (6); and a central guiding part (8), positioned axially-slidably in a front part of the passage of a sleeve (12); and an end threaded part (9) to screw the bolt into the node (10) providing that the least diameter of the central guiding part (8) equals or is bigger than diameter of the end threaded part (9), and, the biggest diameter of the central guiding part (8) equals or is less than diameter of the cylindrical part (7) of the bolt (5), and, providing that the passage of the sleeve (12) has, in the rear part thereof, diameter bigger than the biggest diameter of the front part of said passage in order to form a gap between the cylindrical part (7) and an inner wall of the rear part of the sleeve (12) to a compression, helical spring (13).</p> |
