Maybe this is one of those = things that isn't terribly obvious, but -
having used a variety of screw type clamps - I'm wondering why
plain old spring clamps aren't suitable for this application. I = can't
ever remember having one fail in service. (photos below)

I think they are fine for small diameter hoses for little and/or low = pressure. I doubt they get the clamping force needed for coolant system pressures; = so on a plane I wouldn’t trust them for even small hoses. The spring = wire version concentrates the force on such a small area more likely to = damage the hose.

That’s my opinion; I haven’t researched those clamps.
