<p>A theft-prevention unit (10; 50) for an item, includes a first portion (12) having a spike (16) intended for passing through the item or a packaging containing the item and a second portion (30; 52) provided with an opening (32b; 54b) for inserting the spike and also includes a locking element to prevent the retraction of the spike after the insertion thereof. The two portions are assembled together and maintained in assembled position according to two possible assembly modes: in a first prevention mode, the spike of the first portion is inserted in the opening of the second portion and the locking element is activated such that a user cannot separate the portions without using a tool; in a second provisional assembly mode, the two portions are mutually attached by a provisional attachment member such that a user can separate the two portions from one another without using a tool.</p> |
