Abstract: 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.

Abstract: A re-usable device for closing bags and the like, which may be sealed in a locked configuration by applying a security seal (24). The device (1) comprises two elongate parts (2, 3) the may be superimposed on each other, The first part (2), which is attached along one side of the mouth of a bag to be closed, is provided with a series of locking pins (6, 6') that--on closing the bag--pass into corresponding orifices (9) in the second part the which is attached along an opposite side of the mouth of the bag. The device is locked in this bag closed configuration by means of locking elements (13, 13') that slide longitudinally along internal passages (8, 8') in the second part until the reach a position where they lock the locking pins (6, 6'). The locking elements (13, 13') may be sealed in such configuration by applying a security seal (24).
