An anti-refilling device, designed to be fixed irreversibly to the neck of a container containing a liquid and to be closed by a stopper cap. The device has an axis coinciding with the axis of the neck when it is fixed on the neck, and has an axial dispensing duct for the liquid through which a transverse wall extends, fixed irreversibly to the anti-refilling device and provided with a plurality of traversing channels, each of the channels connecting an external opening, directed towards the outside of the container, to an internal opening, directed towards the inside of the container. The smallest dimension of the external opening is less than a critical dimension determined according to the critical surface tension of the material making up the transverse wall, typically about 0.7 mm, and the smallest dimension of the internal opening is greater than the critical dimension.
