Quite possibly the coolest apparel accessory for the spy-type or someone that just doesn't feel like being handcuffed. The Zipper-Pull Covert Hidden Handcuff Key replaces your stock zipper pull and is non metallic so it won't set off a metal detector. Two for about $7 here.
This could be one of the ultimate HIPS (Hidden-in-Plain-Sight) items – one of our covert non-metallic handcuff keys disguised as a simple zipper pull. These can be attached to any zipper on your jacket, pants, etc. The key remains completely hidden, and is simply pushed out from its housing when required in an emergency. Since the key is attached to its cord, it will not become lost even during the most demanding situations. Includes key.
