The invention concerns a tamperproof cap for a container whereof the neck has a peripheral band, in particular for a cask bung, consisting of a band (1) and a disk (2). The band (1) comprises elastic tab closures (3) located beneath the neck band, upper tabs (4) arranged in the band upper plane designed to be urged to press on the neck end, retaining ribs (5) and rupture slots (6) at the base of which is provided a frangible bridge (11), the upper tabs located at the rupture slots (6) are linked to the band by two frangible bridges (12) and (12'). The disk (2) which rests on the neck edge is maintained between the upper tabs (4) and the retaining ribs (5). When the cap is removed, the frangible bridges (11), (12), (12') are ruptured preventing subsequent replacing of the cap on the container neck in its initial intactness.
