Abstract
Coupling device for rotating tubes essentially characterized in that it comprises a bushing provided at its upper end with a recess for fitting and fixing thereto one of the tubes, while its lower end is applied against the inner face of the other tube with interposition of elastic rings of seal housed in corresponding grooves made in one of these elements, in order to avoid leakage of liquid, the first tube being retained to the second without the possibility of axial displacement but so that it can rotate, by means of a ring, possibly open, attached to the edge of the second tube by means of a nut with internal flange, and having on its internal face an annular rib that fits with certain clearance in a groove provided in the bushing.
