ABSTRACT:
The invention relates to a security seal comprising a flexible strip (7), a locking box (1) attached to a first end of the strip, and a free second end of the strip being insertable through an entry slot (4) in the locking box for non-detachable locking therein. An indicating member (13) is arranged inside the box adjacent a rupturable wall (5) thereof so that, when locking of the free end of the strip is effected, the indicating member is caused to rupture the wall and thereby provide visible evidence of locking.
