What do you call those metal compression bands with the screw tightener?

We used to use them to connect two lengths of hosepipe via a bit of metal tubing shoved into each end! You'd get two of the bands to clamp each end. You slipped them on then turned a screw to reef them tight.

Any idea what they're called so I can look them up?
