Most likely those hose clamps have caused damage to the hose. That hose is designed to work with those hose fittings with no clamps. One mfg specifically states in their catalog "CAUTION: Sealing integrity may be damaged by the use of clamps"
Using clamps cuts the inner liner of the hose and starts a downward spiral. I have seen that hose and fitting assembly hold over 100 psi engine oil pressure without any clamps. The hose is rated to 300-350 psi (depending on model & maker) and the fitting itself to 5000 psi.

I would remove the clamps and very, very carefully cut the hose off the fittings (you will not be able to pull it off!). Do not knick the fittings in the cutting process. Shorten the hose the minimum necessary and re-install on the fittings.

If no clamps makes you nervous, then use either safety wire in two wraps or a Thomas & Betts (ONLY!) tie-wrap very carefully placed between the barbs of the fitting. Pull either down to only snug, definitely not tight.
