The original ones, they self tension themselves as the hose shrinks in cold weather. But they require the use of an original hose.
At very minimum if you have to use a screw clamp due to any reason e.g. aftermarket hose make sure its a band style which is smooth from the inside (like factory SS clamps on older mercedes, BMW, VW/Audi products)
I like to apply a very thin coat of indian head shellac or hylomar to make sure there is no leak ever. (The pitting you see on old flanges is due to the screw clamp loosening up and allowing liquid to pass through)
