摘要

Improvements in threaded joints for the connection of pipes, comprising a coupling element in the form of a sleeve provided with a thread and an inner cone, as well as an oppressor ring which is found in the coupling element and which serves to support an end of tube, characterized essentially by the fact of disposing the end of the oppressor ring facing the inner cone, stepped down in its outer diameter and forming an annular stop on the oppressor ring delimiting the path of tightening the coupling element.
