PROBLEM TO BE SOLVED: To provide a device for forcibly fixing two elements perpendicular to each other, particularly, a device for securely connecting two tubular elements to each other.SOLUTION: The tubular elements 10, 12 each have a square or polygonal cross section partially sectioned by a U-shaped band 22 and include a plurality of pairs of shaped recessed portions 14 in at least one plane, and the band 22 has pairs of complementary protrusions 16 corresponding thereto, protruded and developed on the inside front faces of opposed perpendicular and parallel branch portions 18, 20. The device includes a supporting cylinder 32 which extends between the branch portions 18, 20 of the band 22, which is mounted at one end on a collar 28 protruded and developed along the inside front faces of the branch portions 18, 20, and which has the opposite end formed as an entrance for a screw 30 having an end for engaging with the end of the collar 28 through its screwed hole 28'. The supporting cylinder 32 extends into the tubular element 10 or 12 in the horizontal direction, and has holes 38, 40 starting from holes 26 of the band 22 and aligned along the two opposed faces. |
