It looks like you would just have chain rub against the lock, but that the bike would still be rideable.
The lock appears to be around the chain+chainring. You would get about 1/2 crank revolution before experiencing "chain suck".
Of course, with a freewheel/freehub, you could pedal 1/2 revolution, then backpedal 1/2 revolution, and repeat.
