The warmer the tubing gets and the more pressure it's under, the more likely it is to pop off a fitting.

Yes, quite.
A well done custom loop should never leak.

I've ran it without clamps for years, this is my first ever problem. Not to say its a wise decision, but it isn't something you 100% NEED for every loop.
1/2" ID tubing with 1/2" barbs and no clamps is asking for disaster.
Some setups can get away with 7/16" ID but if the water gets warm enough, or there is a blockage that increases psi, even that can pop off 1/2" barbs.
