Damien I did not intend to say I kew a way to open any belt but all that I have seen in person could be removed easily with vise grips on the shackle protector or bolt cutters on the lock shackle. The radial lock on the tolly boy belts would be more difficult but still using tools to twist the lock would likely be successful. It is just a pin.
Of course in all cases the belt is severely damaged makig escape evident and requiring major repair or replacement.
