<p>A tie-type security seal having a seal body (1) with internal locking teeth (5) in a tunnel (2) and an elongate element (11) having a series of sealing formations (14) therealong. The free end (13) of the elongate element (11) may be passed through the tunnel (2) so that the sealing formations (14) successively cooperate with the teeth (5) on tightening the loop so formed. According to the invention, a locking accessory (9) integral with the seal body (1) is formed with a through opening (15) having a shape substantially identical to the cross section of the elongate element (11) and at least one flexible edge part (16) to adjust itself to the differences in the said cross section in the regions of the regions of the sealing formations. The accessory (9) is foldable with respect to the seal body (1) so that the through opening (15) is superimposed on the open outlet (4) of the tunnel (2) in the seal body. When the seal is closed, the accessory (9) together with the body (cross section) of the elongate element (11) totally blocks the outlet of the tunnel (2), preventing attempts at violation.</p> |
