Self-locking seal
First Claim
1. An electronic seal comprising:
- a portable housing;
alarm circuitry which when actuated provides an alarm signal;
a wire extending from said housing and in electrical communication with said alarm circuitry, whereby tampering with said wire causes actuation of said alarm circuitry;
a locking element which selectively lockingly engages said wire to said housing; and
a coded switch in electrical communication with said locking element which selectively unlocks said locking element to release said wire and prevent actuation of said alarm circuitry.

Abstract
An electronic seal including a housing, alarm circuitry which when actuated provides an alarm signal, a wire extending from the housing and in electrical communication with the alarm circuitry, a locking element which selectively lockingly engages the wire to the housing, and a switch external to the housing in electrical communication with the locking element which selectively unlocks the locking element to release the wire. There is also provided an electronic seal including a housing including alarm circuitry, the alarm circuitry when actuated providing an alarm signal, a wire extending from the housing and in electrical communication with the alarm circuitry, the wire being attached at a first point and at a second point thereof to the housing, a portion of the wire between the first and second points, called a tying portion, being suitable for tying an object, wherein tampering with the tying portion actuates the alarm circuitry, and an adjustment device for adjusting a length of the tying portion.
