<p>1. Connecting angle bracket making it possible to assemble two mitre-cut tubular sections (2, 3), each angle bracket having a main part (4) with two identical branches (7, 8), each branch (7, 8) having small overall dimensions so that it can be located in the interior (9a, 9b) of the corresponding section (2, 3), characterized in that each of the two branches (7, 8) is symmetrically provided with a slide (5a, 5b) and an actuating member (6a, 6b), said slide being provided with a retractable pin (15a, 15b) able to cooperate with an opening (20a, 20b) made in the corresponding section (2, 3) and said actuating element (6a, 6b) is provided with a screw (19a, 19b) passing through the same and a slope (18a, 18b), each branch (7, 8) having the general shape of a cradle (10a, 10b) which can receive the slide (5a, 5b) and the actuating element (6a, 6b), said cradle (10a, 10b) having at one end a slope (11a, 11b) and at the other a shoulder (12a, 12b) said slide (5a, 5b) being located on the side of shoulder (12a, 12b) and said actuating element (6a, 6b) on the side of the slope (11a, 11b) so that, under the action of the introduction of the screw (19a, 19b) into a taphole made in the main part (4), the actuating element (6a, 6b) whose slope (19a, 19b) cooperates with the slope (11a, 11b) of the cradle (10a, 10b) through a vertical displacement forces the slide (5a, 5b) in a longitudinal direction towards the shoulder (12a, 12b) of the main part (4).</p> |
