Ah fair point. They are jubilees albeit with much deeper, bitier teeth and a larger screw. Can't imagine my £2 jobbies were rust-proof. Having said that my old Forge CAI used standard cheapo jubilee clips and that was on the car for 2 years and showed no signs of rust or loosening in the whole time I had it. I'm not dismissing the issue at all but my experience (so far - not had it on as long as you Warren) is that the jubilee clips are fine.
