leak?

I was testing my water cooling system the other night, and sprung a little leak at the begginging, but i tightened the steel hose clamps a little more and the leak was gone, is it safe for me to use this in my case, if it does not leak for another day or two. Or is it likely to leak again?

I would double up on the clamps and but gobs of silicone sealant around the joints- that will garuntee no leakage and give peace of mind.

I personally smear Pvc Cement around the hose before putting onto the barbs,then clamp tightly,it looks a lot cleaner than other sealants since it is clear,also letting it run for 24 hrs on newspaper then you can see leaks,I normally only wait 3-4 hrs(No Patience) if I see no leaks then I feel ok, that's never let me down yet.
