The linear part provides complementary elasticity to the device which contributes to the ejection of the second end of the ring outside the locking means. ## Claims ### Claim 1 An anti-theft device (1) comprising: a ring (2), a locking means (4) to lock (4) the ring in a closed position, and an anti-theft detection means (3), wherein the ring comprises: a body (20) comprising a first end (21) near which the locking means are associated, a second opposite free end (22) designed to be introduced in the locking means to lock the ring, and said body having a circular part (23) extending from the second opposite free end (22) and designed to cooperate with said locking means (4) to lock the ring, and a straight part (24) configured to extend from the at least one circular part (23) opposite the second opposite free end (22), and a curved part (25) extending from straight part (24) such that the straight part (24) is positioned between the circular part (23) and the curved part (25), wherein the straight part (24) is deformable into a curve when the device is fixed to a bottle neck, and revertible to straight shape once the circular part (23) is released from the locking means (4); and wherein the circular part (23) is less flexible than the straight part (24). ### Claim 2 (depends on 1) A device according to claim 1, wherein the straight part (24) is straight over at least 15% of a length of the body of the ring. ### Claim 3 (depends on 1) A device according to claim 1, wherein the body of the ring is made of plastic material. ### Claim 4 (depends on 1) A device according to claim 1, wherein the thickness of the linear part (24) ranges between 1.2 mm and 2 mm. ### Claim 5 (depends on 1) A device according to claim 1, wherein the curved part (25) and the straight part (24) of the body of the ring comprise: a longitudinal rib (6) on the inner wall of the ring, wherein the rib is centered on a height of the ring and extends from an end of the circular part up to the means to lock the ring. ### Claim 6 (depends on 1) A device according to claim 1, further comprising detection means (3) housed in a housing (30) integral with an outer wall of the body of the ring and arranged at the circular part (23) and diametrically opposed to the second opposite end (22). ### Claim 7 (depends on 6) A device according to claim 6, wherein the means to lock the ring (4) accommodated in a rigid enclosure (40) comprise, a notched part (45) designed to cooperate with a crenelated portion (23C) of the circular part (23) on the outer wall of the ring, and adapted to move so as to be dissociated from said crenelated portion. ### Claim 8 (depends on 6) A device according to claim 6, wherein the ring comprises a pin (5) disposed on the outer wall that extends transversely to the circular part (23). ### Claim 9 (depends on 1) A device according claim 1, further comprising a hood application means (7) that comprises a projecting part that extends transversely to a plane containing the body of the ring (2), wherein the projecting part is placed opposite an inner tightening volume (2A) of the ring. ### Claim 10 (depends on 9) A device according to claim 9, further comprising a check-display device configured to check and display in a tamper-resistant manner a price or a price range of an item so the price or price range of the item is identified by the check-display device, wherein the check-display device comprises a means to identify and determine the price or the price range. ### Claim 11 (depends on 10) A device according to claim 10, further comprising a family of rings and/or hood application means in different colors, wherein each color corresponds to a different price range, wherein each ring and/or each hood application means constitutes part of the check-display device. ### Claim 12 (depends on 6) A device according to claim 6, wherein the ring, particularly the housing (30) accommodating the detection means, comprise at least one support surface (62) on which an adhesive price label is glued or on which a price information is engraved. ### Claim 13 (depends on 1) A device according to claim 1, wherein the device is used around a cylindrical body. ### Claim 14 (depends on 2) A device according to claim 2, wherein the body of the ring is made of plastic material. ### Claim 15 (depends on 14) A device according to claim 14, wherein the body of the ring is made of plastic material only and does not contain any metal. ### Claim 16 (depends on 3) A device according to claim 3, wherein the body of the ring is made of plastic material only and does not contain any metal. ### Claim 17 (depends on 1) A device according to claim 1, wherein the thickness of the linear part (24) ranges between 1.4 and 1.6 mm. ### Claim 18 (depends on 8) A device according to claim 8, wherein the pin further comprises a convexity (50). ### Claim 19 (depends on 11) A device according to claim 11, wherein the ring, particularly the hood application means (7) comprise at least one support surface (62) on which an adhesive price label is glued or on which a price information is engraved.
