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end of the shackle inserted into the sleeve bore and wedges and locks to the cable and sleeve when the shackle is withdrawn.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 thermoplastic housing has a chamber open at one end and a thermoplastic rotor is locked axially in the chamber by snap fit ridges and grooves. Two pairs of bores on opposite sides; of the chamber are aligned, with one pair connected by a transverse slot. The rotor has two bores aligned with the housing bores and includes flexible pawl teeth which engage ratchet teeth in the chamber. The teeth rotationally lock the rotor relative to the housing in one direction while a seal filament inserted in the bores is wrapped about the rotor as the rotor is rotated in the other direction. The slot permits the filament to be fixed to the rotor when the rotor is rotated 180.degree. causing the filament to traverse the slot and permit the remaining adjacent bores in the same plane as the fixed filament to be aligned and free to receive the filament free end. The rotor is rotated relative to the housing manually by finger gripped flanges attached to the rotor and to the housing with the filament inserted to wrap and lock the filament to the rotor. The rotor and housing define a channel for receiving multiple turns of filament to enhance the locking action.

Rotatable seal

An improved security seal includes a plastic housing with a chamber open at one end and a plastic rotor which is insertable in the chamber. The housing wall contains bores aligned across the chamber and two annular grooves adjacent the chamber entrance. Tabs are formed adjacent the chamber entrance. The rotor has a bore and two annular ridges near its top. The ridges are relieved complementarily to the tabs. The rotor may be partially inserted in the housing by snapping the lower ridge into the upper groove and locating the tabs in the relieved areas to align all of the bores so that a seal wire may thereafter be inserted through the seal. The ridge-groove and tab-relief cooperation prevent inadvertent relative rotation of the rotor and housing and full insertion of the rotor. With a seal wire inserted, the rotor and housing are relatively rotated to wrap the wire about the rotor. The rotor is then fully inserted into the housing so each ridge snaps into one groove. This and the engagement of teeth on the bottom of the rotor and the chamber prevent removal of the rotor from the housing, relative rotor-housing rotation, and removal of the wire from the seal. Cowls may surround the housing bores to obviate insertion of an object and levering out of the rotor from the housing.

A rotatable seal which includes two inter-fitted relatively rotatable members. A sealing wire is passed through a hasp and through aligned apertures in the members. Relative rotation of the members causes the sealing wire to be wrapped at least partially around one of the members. Relative axial displacement of the members causes the apertures to be mis-aligned and the seal to be locked.
