Abstract: An anti-theft device comprises a notched strap having a free end and an end rigidly connected to a block, which locks the notched surface of the strap in the closed position when the free end is inserted into an insertion slot provided in the locking block. The anti-theft device further comprises theft detection means.

Abstract: An anti-theft device for an item having a peripheral shoulder, comprising two hinged portions each having a peripheral skirt provided with an edge capable of abutting under the peripheral shoulder, with the portions being hinged relative to a peripheral pivot; magnetically deactivatable locking means, which lock the two hinged portions in the closed position, and a detection means wherein the portions are made up of a stationary shell having a general cylindrical shape, the cross-section of which matches the cross-section of the item to be protected and a movable shell connected by a pivot, the stationary shell having a recess opening laterally to allow the insertion of the movable shell in closed position.

Abstract: An antitheft device attachable to an article, formed by two parts, one part comprises a means for remote interaction with a terminal detecting passage of the device, a hinge to allow movement between a protection position, and a release position, one of the parts having, at the end opposite to the movable hinge, a needle able to move in a direction perpendicular to the mid-plane of the device, the other part comprising a housing for receiving the needle, the housing comprising lock configured to allow the release of the needle with an opener, wherein the first part has three retractable cages enabling the needle to move between a retracted position where the tip of the needle does not project beyond the internal surface of the first part, and a deployed position in which the needle is engaged in the complementary housing when the device is in the closed position.

Abstract: 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.
