Claim Text:
1. A device for locking a stopper on a container having a flange, the locking device comprising: a cap with at least one internal groove, the cap being shaped so as to cover the stopper and surround the flange and thereby render the stopper inaccessible; and a collar capable of being housed inside the cap and having lower internal lugs that provide support beneath the flange in order to cause the collar to interlock with the container and the collar having external lugs that engage with the groove in order to cause the collar to interlock with the cap, the cap further including at least one frangible zone capable of rupturing so as to permit the opening of the cap and the withdrawal thereof relative to the flange, the collar being formed from a band that is extended by tenons that surround the stopper, the collar being provided with at least one deformable and breakable bridge that is arranged opposite the tenons and able on the one hand to elastically deform radially in order to permit the forced insertion of the flange into the collar and on the other hand to be broken in order to permit the withdrawal of the collar relative to the flange and then the withdrawal of the stopper from the container.
