Disclosed are devices, systems, apparatus, methods, products, and other implementations, including a seal device that includes a housing and a controller disposed inside the housing, with the controller including at least one sensor configured to measure motion data to detect motion of the seal device, and a communication module. The seal device further includes a seal connectable to the housing, with the seal including a shell and a conductive wire connectable to the controller. The controller is configured to cause the communication module to transmit at least one signal at least in response to one of, for example: a) determination, based on the motion data measured by the at least one sensor, of movement of the seal device, and/or b) detection of structural damage to the seal.

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 lock, suitable for locking an airline cart, the lock comprising, a body, at least two locking arms housed within the body, and a biasing means, the biasing means arranged to urge a first locking arm and a second locking towards a maximum limit. The at least two locking arms are configured to resist removal of a hasp inserted into the lock. The at least two locking arms are tied to one another such that the at least two locking arms may reversibly move relative to one another, and an amount of movement of a first locking arm relative to a second locking arm is up to the maximum limit. A hasp for use with the lock, and kit of parts, is further disclosed.

The present invention discloses an anti-theft method for wire lock and the corresponding wire lock, by improving the structure of the lock body of wire lock, when the lock hole of wire lock is inserted for the first time, the structure of the lock body changes, so that the lock hole can not be inserted again, and the anti-theft effect of wire lock is improved.
