Master Lock StreetCuff Bicycle Lock

Intended to be used to lock your bicycle to a pole, it is curious that these are exactly the right size to act as very confining Leg Irons. They have a 10 pin ace-key type lock which when unlocked allows the bows to move in and out of the lock case. Once pushed in, while a bow is in its case, they engage and lock the bows solidly in place. The parts that encircles the bike or pole are coated with a tough rubbery substance to prevent scratching. The pivoting connecting link is quite strong.
