<p>Engagement lock comprising two members (1 and 2) which can be interlocked after they are passed through the locking rings (3, 4) of a container. The first member (1) is rod-shaped and has a head (5) which cannot pass through the locking rings (3, 4). Opposite the head it has an insertion end (6) of metal. The lock cannot be broken by bending the rod-shaped body from side to side because this body has a core of steel wire (12) whose elongation extends into the head. The elongation of the steel wire (12) is embedded in polyacetal which also forms the head (5), and the layer of polyacetal around the steel wire (12) has one or more annular grooves (14) in which it can break by bending the rod-shaped body.</p> |
