Yeah, it sounds similar, but in a worm clamp, the "screw" engages slots in the band.
In a Fuel Injection Hose clamp, the screw tightens against a nut. They get MUCH tighter.
Richard Martin posted a great picture of what I described, and yes, every auto parts store has them. You just have to say "Fuel Injection" when you're asking for hoses or clamps.
