Hose clamp

An adjustable metal ring, wire, or band placed around a hose where it connects to a metal pipe, to prevent leaks and to keep the hose in place. Hose clamps are tightened in one of three ways. In single wire clamps, it is tightened by spring tension of the clamp. In worm-gear clamps, by a worm screw. In strap-and-bolt clamps, by a screw. The British term is "hose clip".
