A rotatable connector joint formed by a main joint body having an axial passage and a ring groove, followed by an axial narrowed portion with a bevelled edge, followed by another widened portion, with a supporting wall for a hermetic O-ring used during an insertion of a terminal end of a rotatable joint body into the main joint body. The rotatable joint body includes a supporting wall for the ring, followed by a hexagonal external projection. The rotatable joint body including at its other extremity, a male clamp or a female clamp, with external screw threads or internal screw threads, the latter being equipped with an axial passage and having, at the front extremity, a narrowed portion which, with the insertion of a cylindrical tool with a tapered point, expands the terminal end and accommodates it in the bevelled edge and ring groove of the main joint body, locking the rotatable joint body axially. The invention aims at simplifying and making faster the locking process for a rotatable joint connector, reducing the manufacture and assembly stages, and consequently, its cost. |
