Same situation with the '91 200q bypass valve. I have two suggestions:
(1) Relax, as I am doing, and just keep an eye on it. It's easy to peek at
it whenever the hood's open (at least it is on the '91) and if it's fairly
snug to begin with, may not need to be clamped. Or, when I get a chance
I'll get around to:
(2) Twist a couple of turns of 14 ga copper wire around the end of the hose
(with almost NO squeezing of the rubber) _before_ sliding it (hose) onto
the valve fitting. If you're careful not to overtighten the wire, the hose
still can be pushed onto the fitting with a little additional effort
(lubricate with water?) and will resist popping off.
