The invention relates to a seal device (1) comprising a locking pin (10) and a sleeve (20), said locking pin comprising a head (11) and a rod (12) consisting of a throat (13) which cooperates with a locking ring (24) disposed in the sleeve (20) in order to lock the sleeve onto the pin by insertion. The sleeve also comprises a first transponder (30) accommodated in the upper part of the sleeve at a depth (P) which is greater than the height (H) of the rod (12). The locking pin also comprises a second transponder (20) disposed on the outer periphery of the rod (12). Each transponder includes storage means for storing at least one unique identification code. As a result any unauthorized manipulation of the seal device can be detected., even in the event of the complete replacement thereof after breakage.
