Abstract
A high security lock includes a shackle having two ends and a lock body having openings for receiving the ends of the shackle. A latch in the lock body has a catch movable into engagement with the shackle for securing at least one end of the shackle in the body. The latch is releasable to allow the one end of the shackle to move clear of the body to open the lock. The shackle is made of a shape memory effect alloy having a characteristic that its yield strength increases when work is impressed on it, so that cutting or breaking the shackle with common tools is more difficult and time consuming than with other shackle materials. The lock thus provides a level of security substantially superior to conventional locks.
