ABSTRACT:
The present invention relates to fast-fit unions for removably joining pipes, wherein a tubular lock element loaded by a spring carries on its inner wall three teeth offset axially of the union with respect to one another, the central tooth being provided opposite the other two so that, to unlock the two elements of the union, two successive inward displacement maneuvers must be exerted on the lock element, consequently allowing the compressed fluid time in which to be evacuated to the atmosphere.
