JOINT FOR THE CONNECTION OF A SECONDARY DUCT TO A MAIN DUCT
A joint (1) for the connection of a secondary duct (B) to a main duct (A) provided with a cutout (C) having predefined shape and dimensions. The secondary duct (B) is inclined with respect to the main duct (A). The joint (1) comprises:- a tubular element (2) provided with a first thread (3) on a first external portion thereof (4) and with a second thread (5) on a second internal portion (6) thereof;- at least one ring (7) provided with an internal thread (8) which is complementary to the first external thread (3) of the tubular element (2); the ring (7) can be screwed onto the first external thread (3) of the tubular element (2);- at least one first shell (9) whose shape and dimensions are complementary and exceed those of the cutout (C) for its easy insertion within the main duct (A) through the cutout (C) and its arrangement so as to overlap the cutout (C), with consequent complete occlusion thereof, with a perimetric border thereof (10) in abutment against the internal surface of the main duct (A) at the edge (D) of the cutout (C); the first shell (9) comprises an inclined tubular channel (11) provided with an external thread (12) which is complementary to the second thread (5) of the tubular element (2) for the coupling of the element (2) to the channel (11) following mutual screw coupling;- at least one second shell (13) whose shape is substantially complementary to the shape of the external surface of the duct (A) and whose dimensions exceed the dimensions of the cutout (C); the second shell (13) is provided with an inclined tubular body (14) suitable for the accommodation of the tubular element (2) and of the channel (11).The clamping of the ring (7) on the first thread (3), with the ring (7) in abutment against the terminal front of the inclined tubular body (14) of the second shell (13), causes the clamping of the edge (D) of the cutout (C) between corresponding perimetric borders (10, 15) of the first shell (9) and of the second shell (13).
