A closure device for a container (2) for liquids comprising a pouring member (4) which has an internal cavity (13) and a pouring opening (15) and which is positioned on the mouth (3) and extends coaxially relative to the neck (1), a closure member (12) disposed in the cavity (13) of the pouring member (4) and movable axially relative to an annular abutment (14) to allow the liquid to come out and to prevent fraudulent admission of liquid, a cap (16) for opening and closing the pouring opening (15) as well as removable sealing means for permitting initial opening of the cap (16). The device comprises a sealing cover (17) fitted on the cap (16) and extending axially, with a sleeve (19) from the top of the cap (16) beyond the region in which the pouring member (4) bears on the neck (1) of the container, the cover (17) having at least one pair of weakening lines (20, 21) for the tearing of the region (23) disposed between the lines, at least one weakening line (22) which extends circumferentially around the sleeve (19) intersecting at least one of the lines constituting the pair of axial lines (20, 21), a tab (24) of the cover being provided at the top (18), adjacent the cap (16), for the pulling of the region (23).
