<p>A device for the forced locking of two elements oriented orthogonally to one another, especially suitable for steadily connecting and constraining two tubular elements (10), (12) with quadrangular or polygonal section which are partly delimited by a U-shaped band (22) and comprise, on at least one face, a plurality of pairs of shaped recesses (14), whereas the band (22) is correspondingly provided with pairs of complementary projections (16) developed projecting on the inner front of the opposite vertical and parallel branches (18) and (20) thereof, characterised in that it comprises a bush (32), extending between said branches (18) and (20) of said band (22) and fitted, at one end, on a collar (28) which develops projecting along the inner front of said branches (18) and (20), whereas the opposite end of said bush (32) constitutes the inlet for a screw (30) the end whereof engages in a threaded hole (28') delimited by the collar (28), the same bush (32) being extended transversally in the tubular element (10) or (12), provided with aligned holes (38), (40) along two opposite faces, starting from a hole (26) of the band (22).</p> |
