Warm the end of the hose in hot water and fit warm with 2 good jubilee clips, can't imagine it coming apart. I used this kinda hose for years without prob.
Personally, I'd be tempted to try making an inline joint from either 22mm or 28mm copper. If the hose will go over the 28mm when you soak it in boiling water, that would obviously be the better choice. This is how I make my hose joins up, (ignore the vent and tap in the middle of this one):
With the olives, I've found that half to a full turn or so of a compression fitting just to compress the olive slightly so that it becomes a tight push fit onto the pipe, rather than their usual slop fit, before soldering makes for a solid join.
We use 316 "t" and brass barbs without issue all the time ,looks ok with the "0"clips on .........was the pipe a good fit on the barbs?,have you seen any reason the jubilee clip joint failed?...normally i have to cut the pipe from the barbs when dismantling a joint,regardless of the fixing method...
Did you have the pipe clipped or did you have a 1" pipe flailing around at 1am?
With decent rubber hose once its pushed on the barbs I cannot get it off without cutting it. A clip should hold it fine I'd have thought. Probably temperature related with the PVC.
Factory I worked in used quality 3/8" reinforced piping from the solid pipe to machine parts which needed to move along tracks and you could see the reinforcing braid parting when the line was getting ready to go then it would start to look like an anaconda eating a goat. I wouldn't use any plastic pipe anywhere it was not easily accessible.
