ABSTRACT:
A security seal includes a first seal member having a first locking portion and a first detection circuit portion. A second seal member has a second locking portion and a second detection circuit portion. The first locking portion is engagable to the second locking portion to engage and irretrievably lock together the first seal member to the second seal member. Engagement of the first seal member to the second seal member operatively connects the first detection circuit portion to the second detection circuit portion to provide a combined detection circuit throughout the security seal. In a preferred embodiment, the first seal member includes a spear having the first locking portion, and the second seal member includes a sleeve having the second locking portion. The spear is insertable into the sleeve to engage the first locking portion to the second locking portion, and to thereby engage the first seal member and the first detection circuit portion to the second seal member and the second detection circuit portion. Breaking of the security seal will break continuity of the combined detection circuit portions, which continuity is checked for evidence of tampering.
