Crimped (permanently deformed) hose clamps - ear clamps and similar designs closed with pincers to give tamper-evident, vibration-proof retention of hose on fittings. Popular in series production and automotive duty for repeatable clamping without re-tightening. Select by the closed diameter range matching the hose OD, and replace rather than reuse after opening.
