Knot formed from a functional combination of two elements, an inner web made from two parts (1 - 1') with an omega-shaped cross section, in which corresponding grooves (8) are defined opposite and crossing each other, and a tubular encasing element (2) which houses inside it the web (1), so that the grooves (8 - 8') of the latter are placed in correspondence with the openings of the encasing element (2), which has notches (7) opposite the ends of the grooves (8) in order to receive inside it the corresponding bars (3), that can be secured to the knot by any means and which are at an angle defined by the grooves (8). At the knot can meet further bars (6) which cross orifices made for such purpose in the knot, specifically in the flaps (4) which frame the grooves (8) and which leave the latter free. <IMAGE> |
