ABSTRACT OF THE DISCLOSURE This invention relates to a stopper device for a recipient with threaded neck, comprising a tapped stopper whose lower part is attached to a guarantee strip by a zone of connection with low mechanical resistance, said strip presenting an elastically deformable, inner, annular bead adapted to clip beneath a holding flange made on the lower periphery of said neck by forced screwing of the stopper and an outer peripheral boss separated from said bead by a zone with controlled elastic deforma- tion, wherein the upper face of the boss and the lower edge of the lateral wall of the stopper comprise at least one tooth and/or at least one notch, said tooth being intended to be temporarily housed in said notch during screwing when said bead is in abutment on the holding flange in order to avoid any relative displacement of the stopper with respect to the strip and to ensure trans- mission of the effort of clipping without deteriorating the zone of connection.
