IME I've NEVER had a *genuine* Jubilee or JCS Hi-Torque ones fail on me in terms of popping off, usually end up crushing the pipe or going through the silicon before the actual clamp fails.
If you're really having problems, take a look at Murray clamps - they're reasonably pricey, but they will not fail.
