Device for coupling hollow bodies, characterized in that it is constituted by two annular pieces in a metallic plate, each of which has a geometrically continuous helical thread, these fillets being obtained by a stamping by means of matrices and countermasters of radial action that at the same time they determine material interruptions in one or in the two filateados that together define axial strips so that said parts are complementary threaded in order to be associated with two bodies object of mutual coupling this is achieved by carrying out the threading of the cited pieces.
