摘要： A tubular axis connection system, of the type comprising a screw clamp (12) and a screw (3), allows the required positioning between clamp and axis upon tightening the 5 clamp itself through the correct alignment of the clamp screw, without the intervention of additional devices, wherein: the screw (3) of the clamp (12) has a central cylindrical section (8) and the tubular axis (1) has a notch (7) equipped with a cylindrical surface with shape 10 complementary to said central cylindrical section (8), apt to couple to said central cylindrical section (8); and the clamp (12) has a clamping seat (16) of the screw (3) comprising two matching surfaces: a first matching surface (18) corresponding to the distal end (19) or 15 tailing end of the central cylindrical section (8), having a matching (22) with larger constant diameter than the diameter of the central cylindrical section (8); and a second matching surface (20) corresponding to the proximal end (21) or heading end of the screw (3), having 20 a section with diameter (26) increasing from the central cylindrical section (8) to the head of the screw (17), the clamping of the screw (3) involving the translation of the central cylindrical section (8) of the screw (3) in the direction of said notch (7) until implementing the 25 above-mentioned coupling thereto the correct positioning of the clamp (12) with respect to the tubular axis (1) corresponds, said matching (22) being formed by two joining grooves, a first joining groove (23) between the matching (22) and the central section (8); and a second 30 joining groove (24) between the matching (22) and the threaded section (9), the first joining groove (23) being with truncated conical shape; the second groove (24) having a truncated conical section, too, with a greater conical angle with respect to the previous one.
