Does this fitting on my CPU block safe?

So this is my first water cooling system and I want to make sure I'm doing things safely.

This current setup has been leak tested for over 48 hours, but the more I look at my CPU block the more I wonder if I should change how it's hooked up.

In the pictures below, the clamps have to be staggered a bit to fit. Both clamps fit over the barb (the the bottom one being 2-4 cm within the end of the barb itself.

Considering I've leak tested for 48+ hours I didn't know if it would be worth the hassle to tear this apart and re-configure or not?

 
It's kind of hard to tell from the small pictures, so what do you think is a problem?
 
Should have went with compressions there, but if it didn't leak for 48 hours, I dont think it's gonna.

What size tube and barb?
 
ID 1/2 OD 3/4. Compression is used everywhere else but the fittings wouldn't work on that block because the ports are too close together.

The only concern I had what that the lower tube clamp is over the fitting completely, but only by a 3-4 cm as opposed to the top one which is all the way down the barb. It's going on 50+ hours now with no issues so I guess I'm ok?

Just didn't know if I should yank it out and do the worm drive clamp or whatever it's called?
 
Does that rationale makes sense? Or since I've been stable for so long I should be set?

I don't plan on moving the computer around much at all. Maybe once every two months but being very careful with it if I do. If I do plan on moving it does that change things a bit?
 
I think you're fine. I would have used worm-gear clamps, but as long as the clamp is below the lip that the barbs have, it's not going to slide off.
 
I went ahead and got the worm-gear clamps, they fit very snug over the tubing without being over the barb and tightened down, so when I did tighten I didn't have to turn the screwdriver terribly much. I made sure the tubing isn't moving, but that I didn't rip into the tubing or collapse the barb.

Since I never did remove the tubing going into the CPU block how much longer should I leak test again. I'm at work now and it is leak testing, so by the time I get home that will be another 9 hours or so.
