A radio-frequency identification fitting ring assembly includes a fitting ring having a ring portion and two sheet portions that respectively extend outward from a same side of the ring portion. The sheet portions are clamped to be in contact with each other and respectively have a through hole. A fixing member passes through the through holes and has a first expanded portion and a second expanded portion on two ends of the fixing member, respectively, to restrict the two sheet portions. A radio-frequency identification member is disposed on the first expanded portion. A part of the radio-frequency identification member is exposed out of the first expanded portion. When the present invention is used, the fitting ring fits around a hose clamp for fixing, and the radio-frequency identification member could be read or written by a read/write device for marking or identifying an information related to the hose clamp later.

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 security sealing device including a sealing element, an integrated circuit and an antenna connected to the integrated circuit, the integrated circuit and the antenna forming a RFID circuit. The security sealing device is characterized by the fact that said sealing element is conductive and is forming a part of said antenna.

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.
