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.
