An anti-theft device (1) comprising a ring (2), means (4) to lock (4) the ring in the closed position, and anti-theft detection means (3), wherein the ring comprises a body (20) that has 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, and at least one circular part (23) extending from the second end (22) and designed to cooperate with said locking means, characterized in that the body of the ring comprises a linear part (24) that is arranged to extend from the circular part (23) opposite the second end (22). 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. |
