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.
Security seal comprising a seal body defining a tunnel having first and second open ends and being formed internally with at least one locking tooth, and a flexible elongate element having a free end, the elongate element having a series of sealing formations along its length so that, on insertion of the free end through the said first end of the tunnel and on it being pulled through the second end of the tunnel, the sealing formations cooperate with the said sealing tooth in a manner similar to a ratchet, preventing withdrawal of the elongate element from the first end of the tunnel, a locking accessory integral with the seal body and formed with a through opening of a shape substantially identical to the cross section of the elongate element, said through opening having an inner edge, adjustment means for adjusting the cross section of said through opening to adapt to differences in the cross section of the elongate element in regions of said sealing formations, said inner edge of said through opening having a flexible tab which is said adjustment means, the accessory being foldable with respect to the seal body so that said through opening in the accessory becomes superimposed on the second open end of the said tunnel in the seal body.
Security seal according to claim, wherein the sealing formations comprise stepped depressions on the flexible elongate element.
