Quick coupling coupling, characterized essentially by being constituted by two elements, of which one of them is provided with an appendix for plugging a tube of any nature; while the second element is a nut that threatens on the first, whose nut is partially hollow and is provided in its interior with a presser lip that retains the terminal of the tube and holds it by progressive tightening as it progresses the threading of the nut imprisoning the tube against said appendix.
