I'm after two "hook locks" for the sliding doors on our boat. They don't have to be super secure, it wouldn't be too difficult to break windows or even lift the doors off the sliders.

They are possibly something like this:-

the 'hook' is much simpler, just an arc of metal that is retracted with the key and has significantly more reach.
Any ideas for a supplier anyone?
