A seal housing body, extruded AL or molded plastic or metal, has cavity portions communicating through an interface region formed by one at least one frangible projection protruding from the first body into the cavity, a first cavity portion for receiving a locking body, the second cavity portion forming a shackle receiving passageway. The locking body has a channel inclined relative to and in communication with the passageway. A spring in the channel urges a shackle locking ball up the channel partially into the interface region, the ball, having a diameter sufficient to pass through the passageway, is captured in the channel by the at least one projection. The locking body has indicia and/or flanges, at one or both opposing ends, to provide tampering evidence. The channel is offset from the locking body's central plane forming a single channel side wall to preclude trapping the ball by tampering.

Tamper evident security seal

One end of a stranded steel cable is attached to a cast zinc seal housing having a chamber in which a steel sleeve with a tapered bore is positioned. The sleeve in one embodiment is fixed to the housing in the chamber or may be displaceable and captured in the chamber in a further embodiment. A serpentine clip locking member captured in the housing chamber resiliently radially grips the a second end of the shackle inserted into the sleeve bore and wedges and locks to the cable and sleeve when the shackle is withdrawn. The sleeve precludes damage to the softer zinc housing by the locking member when the locking member is displaced in the housing chamber. Various embodiments are disclosed. In a further embodiment, the one end of the cable exits the housing in a plane different than where the second end enters the chamber to enhance ease of insertion of the second end into engagement with the locking member.

Security seal and lock with enhanced bore sleeve

A filament seal for use with stranded or solid metal or thermoplastic filaments comprises a segmented housing defining a chamber in which a locking insert element is positioned, the insert comprising a thin circular disk of hardened stainless steel with a plurality of radially inwardly extending resilient cantilevered fingers each terminating with a tapered sharp pointed tip in abutting or closely space relationship defining a space substantially smaller than the diameter of the filament. The inserted filament bends the fingers and is softer than the insert, the tips digging into the filament during use. When the filament is withdrawn, the finger tips dig further into the filament severing it. If the filament is rotated in an attempt to thread the filament out of the insert, the insert rotates with the filament due to the digging action of the tips into the filament, precluding filament withdrawal from the insert. A hardened steel washer is adjacent to the insert locking element to preclude bending the tips in the withdrawal direction and breakage of the tips, and precluding defeat of the locking action. The fingers are dimensioned to resist distortion in lateral directions during twisting. Various embodiments are disclosed.

A housing has a rotor receiving chamber with filament receiving bores lying in a plane normal to the rotor axis of rotation, a rotor being rotatably received in the chamber. The rotor and housing have complementary locking shoulders for axially locking the rotor in the chamber. The rotor has a pair of filament receiving bores aligned with the housing filament receiving bores. The rotor has an annular rib in the plane of the bores defining upper and lower rotor sections. The locking shoulders are in the lower section of the rotor and are located between the plane and the closed end of the chamber, at which end the rotor and housing have a complementary ratchet and pawl mechanism for allowing only one way rotation of the rotor relative to the housing for securing the filament to the rotor. The rib guides the filament wrapped about the rotor into sub-chambers formed by the rib to minimize blockage of the rotor bores by the locking and wrapping of one filament end to the rotor in an unlocked shipping state of the seal. This permits the free end of the filament to be secured to the other bore in the rotor at the time of sealing of the seal to an article.

Rotatable seal

A seal and lock mechanism employs a cable and a mechanism for securing a free end of the cable to the seal by a wedging action within a tapered housing bore employing wedging means such as balls and the like. The wedging action is enhanced by roughening the surface of the wedging means or otherwise improving their resistance to displacement with respect to the surface of the cable.
