A tubular connector of the type with a revolving locking nut particularly adapted for flexible oleodynamic hoses and the like, comprising a nipple fitting (1) with a shoulder (3) for the abutment of a locking ring (6); the connector comprises a conventional revolving nut (10) for locking the sealing head (7) of the nipple body (1) on the end of the tube or nozzle of a user device, and the nut (10) has, in a rearward position, an annular rim or lip (10b) that protrudes coaxially from the threaded cavity and has such dimensions as to allow its insertion on the nipple (1) and its subsequent partial deformation by pressing, after fitting on the tubular nipple body, so as to reduce its diameter and thus create a mechanical retention element (10b) that acts as a spacer between the nut (10) and the shoulder (3) of the nipple; at least one mechanical retention element, substantially an internal annular rib (6b), is furthermore provided inside the locking ring (6) and is adapted to be correctly located with respect to the nipple before locking by pressing. <IMAGE> |
