A clarification: The hose clamp doesn't loosen, it is the hose that changes. How it happens depends on the chemical composition of the hose.
Plastic hose under pressure from the clamping system, cold flows and no longer seals whether on the suction side or pressure side of a system.
Think all those leaky air lines on a semi or compression fittings on water lines. Even the rubber radiator hoses lose resilience and develops a compression set with time and eventually leaks antifreeze.
Net result is that if you use spiral clamps it is good practice to re-tighten them if you wish to avoid a leak. Part of my spring ritual for my dump truck, other vehicles and the head in the sailboat.
The above doesn't help if the spiral clamp was not installed on the hose barb fitting correctly. Two clamps, one near the end of the hose once all the way on the hose barb, the other near the end of the hose barb farther back on the hose, is a better practice than a single clamp. Even better is to use a different seal design altogether.
This is BS, I work with hose clams everyday and what your saying is just not right. I have never in my 55 years have had a hose clamp loosen up! hoses fail rubber breaks down plastic cracks but Hose clamps do not back off on there own.
