What is the small hole used for locking the cuffs twice called?

Explanation:
The main idea is recognizing the safety feature on handcuffs that prevents them from tightening further. The small hole is specifically for activating the double-lock mechanism. When a tool or the proper key is used in that hole, the mechanism moves into a secondary position so the cuff can’t tighten, even if the wearer pulls on the chain. This protects against excessive constriction and injury. Once double-locked, the cuffs can still be opened with the normal key, but they won’t tighten any more. The other terms describe generic parts or features, but the described function—locking the cuffs twice via that hole—is the double lock.
