A closure for a closure for container for liquids comprises a pouring member (6) which has an internal cavity (10) and a pouring opening (12), a valve member (9) disposed within the cavity (10) of the pouring member (6) and a movable to allow the liquid to come out and to prevent fraudulent admission of liquid, a stopper (16) for opening and closing the pouring opening (12), a sleeve (15) housed inside the stopper (16) and fixed there-to, the sleeve (15) having threaded means (14) for screw connection to the external wall (6a) of the pouring member (6), as well as a security ring (22) which can be broken upon initial unscrewing of the stopper (16). The stopper (16) and sleeve (15) have means (18,19,20,21) for mutual coupling by means of axial movement. The stopper (16) has a collar (17) which is coaxial with the axis of the pourer (6) and which is inserted in a leaktight manner in the opening (12) thereof. The ring (22) is connected,by means of breakable bridges (24), to the free edge (15d) of the sleeve (15) which is fittedin the stopper (16).
