Icepack, They are the best clips for coolant systems. Firstly they are designed to apply the correct pressure but do require good hoses and clean connection points.
They apply constant pressure and don't loosen but more they apply even pressure to the whole circumference and don't damage the hose end through distortion. The biggest failing of the jubilee clip is in not providing full circumferential pressure without damage to the hose and of course how tight is tight which also has a detrimental effect. Most hoses fail on the hose side of the fitting when they are used for this very reason.
In most instances you can use water-pump pliers but the correct pliers are so much better and easier to use and starting at around a tenner, no contest!
There are screw clip versions with a sliding inner sleeve that are also preferable to jubilee clips. Sizing. These clips are bought as per hose sizing, so if you have a 12mm hose you buy a 12mm clip.
