An external tubular body of a locking joint includes an axial cylindrical passage followed by a short radially widened section to accommodate a tube. Another further radially widened section is formed to receive a hermetically sealing O-ring. A section with a short, conically tapering surface followed by a straight section leads to an inverted conically tapering section to facilitate insertion of a glove. The glove is a tubular body with a plurality of longitudinal cuts extending to a frontal ring relief. The cuts form flexible stems, externally equipped, at an opposite extremity with a back bevelled edge ring and, internally by two rows of teeth. The teeth reduce the internal size of the glove to bite into an outer surface of an inserted tube to lock the tube within the external tubular body as the back bevelled edge ring is slid along a tapered surface of the external tubular body during withdrawal of the tube from the tubular body.
