A theft preventing device for an article having a substantially cylindrical end with a substantially ring-shaped bulge, e.g. a bottle or container. The device comprises a releasable body having a clamping means gripping the cylindrical end when in the closed position, and a locking means for preventing the clamping means from being opened unless a special tool is used. The body comprises of a substantially tubular element with a larger diameter than the ring-shaped bulge, and comprises a member that is movable relative to the tubular element between a closed position in which it defines a cross-section smaller than that of the ring-shaped bulge, and a released position in which it defines a cross-section greater than that of the ring-shaped bulge.

[ What is claimed is:] [1.] A theft preventing device for articles having an end which has a swelling and a central axis such as a bottle or a flask, said theft preventing device comprising:an interior element having at least one protuberance directed toward the central axis,an external tubular element, said external tubular element being movable with respect to said interior element along the central axis between a position in which said interior element and said external tubular element work in cooperation to push back said protuberance in the direction of the central axis, and having an unlocked position in which said external tubular element releases said interior element to allow a radial separation of said protuberance; anda locking means having a radially movable metal blade to prevent the opening of the article without using a specific tool,wherein the tool unlocks said locking means by magnetically displacing said radially movable metal blade.
