The stopper device (1) according to the invention comprises a base (10) adapted to be fastened to a neck of a container (2) and a cap (20) movable relative to the base between closed and open positions. In order to make said device more tamper-evident, the invention proposes, on the one hand, a strand (50) which, in an unaltered configuration, extends lengthwise along the periphery of the cap and whereof the first (51) and second (52) longitudinal ends are connected to the cap frangibly and non-frangibly, respectively, and, on the other hand, a hook (60), which is secured integral with the base, protruding toward the outside of the base, and which is adapted so that, when the strand is in the unaltered configuration thereof, it retains the running longitudinal portion (56) of the strand, in a direction substantially parallel to the axis (X-X) of the base, so as to block the movement of the cap from its closed position to its open position. Furthermore, the first end of the strand is integrally provided with a tab (53) for manually driving the strand so as to detach the first end of the strand relative to the cap, by breaking the frangible connection between them, then for moving the running portion of the strand away toward the outside of the cap, by plastic deformation of the non-frangible connection between the second end of the strand and the cap, until the strand reaches an altered configuration in which the cap is free to be moved from its closed position to its open position without the running portion of the strand being retained by the hook. |
