A locking device includes a lock body, a hasp and a seal. The lock body includes a hasp locking latch pivotally disposed therein and a seal locking latch pivotally disposed therein. The hasp is disposed at the lock body and movable between an open state, where a free end of the hasp is external the lock body, and a closed state, where the free end of the hasp is within the lock body. The seal, when inserted into the lock body when the hasp is in its closed state, engages the hasp locking latch to pivot the hasp locking latch to engage and lock the hasp in its closed state, and the seal, when inserted into the lock body, engages the seal locking latch to lock the seal within the lock body. The seal includes a frangible portion that is configured to break the seal into first and second portions.

The invention concerns a device for marking a commercial article, comprising two separable parts: a first part (12) including an axial spike (14), a second part comprising an orifice for axial insertion of the spike and means for locking the spike inserted in said orifice. One of the parts, referred to as the attachment part, comprises an attachment: member (32) that is able to pivot between a first position in which a free end of the member is far away from the attachment part and a second position in which the free end is disposed in a housing (50) of the attachment part. The attachment part is configured so that the free end (32a) of the attachment member is blocked in the housing (50; 108) by the presence of the other part of the device that is locked to the attachment part by way of the spike (14) and its locking means.

A tamper-evident, single use, ring assembly, is assembled from first and second interengaging broken rings (1, 2). The first broken ring (1) is of a first material and the second broken ring (2) is of a second material. A break in the ring of the first material is offset circumferentially from a break in the ring of the second material. The assembly of the rings forms a closed ring assembly which can be cut through in the region of the break in the ring of the first material to open the ring assembly. At least one of the rings (1, 2) of the ring assembly is resiliently stressed in its assembled state such that, upon cutting through of the ring assembly, the confronting ends of the assembly move apart.

A multifunctional label includes a radiation protection layer which is designed to predeterminedly reduce the transmission of electromagnetic radiation in a given wavelength range. The multifunctional label further includes a gas barrier layer, which is designed to reduce the transmission of a gaseous substance in a predetermined manner. The radiation protection layer and the gas barrier layer are directly or indirectly coupled to each other in the common multifunctional label.
