摘要： The bushing (3) as such constituting the main (1) tapping or bypass and designed to radially cross the latter's wall through a bore (2), is provided at its inner end with a truncated cone-shaped expansion (5) acting as a means deforming a gasket (6) when said bushing tends to move outwards driven by a nut (9) which acts on a threaded sector (4) of the outer bushing end, and using the outer surface of the main (1) as a supporting base. The nut (9) acts on the wall of the pipe (1) with a washer (8) in between and a perimetric expansion (7) with which the gasket (5) is provided, in order for the latter not to be driven outwards by the actual bushing (3) whilst the nut is being tightened.
