2-Ear Pinch Clamp, Zinc Plated Steel, 0.433 - 0.512 Inch Clamping Range, 0.276 Inch Width

Zinc-plated steel construction and the two-ear pinch design make this clamp well-suited for exactly that kind of application. The way these work, you close the first ear all the way, then bring the second ear down until the first opens back up just slightly, about a 1/16 inch gap. That sequence builds a spring-like tension into the clamp so it stays tight even as vibration cycles and the hose material shifts over time. Oetiker specifically calls out heavy vibrating equipment as one of the primary use cases for this design, so you're in good shape there.
