This device was invented to catch an automobile thief by snapping and ratcheting closed around someone's ankle if they depress the clutch pedal without first disarming it with use of the key. As an added bonus, it constantly sounds the horn alerting the owner to the cuff being engaged.

Nice !
Already seen a similar idea in a sci-fi french comics (with a "wolf trap").

But I prefer the Magnavolt system : https://www.youtube.com/watch?v=bMtqRir7dco

Good one! There's also the one from "For Your Eyes Only" -https://www.youtube.com/watch?v=5h4joX0iF9A

Given the number of bikes professionally stolen and then shipped to Eastern Europe over here, I would actually appreciate something like that.

From old Russian 1966 movie "Beware of the car" - the wolf trap as car anti theft system.
