A cushioned P clamp with a 19.1mm inside diameter, suited to AN10 hose. The rubber-style cushion inside the metal band absorbs vibration and stops the hard clamp edge biting into the hose cover, while also keeping the metal band from contacting the fitting or braid directly. AN10 lines are usually carrying meaningful volume, so they are heavier and swing further when unsupported, which makes proper clamping more important than on small lines, not less. Fix clamps to solid points on the chassis or engine bay rather than to thin trim panels, and keep them close enough together that the hose cannot slap under load.
