Not seen any sold for watercooling but you can get similar to clamp car brake, fuel and vacuum hoses.
Have a search for Laser 7254 Hose Clamp Set for up to 15mm OD, or there are plier type ones available. Haven't tried to do it myself though.

I have used straight jawed mole grips before
In the days before I used quick disconnects
Also called locking pliers
