On carbon frames I've used, they have had a single bolt clamp like this one, so it should be fine. Personally, I'd like to use a slightly bigger clamp and one of those rubber size-decreasing rings to avoid cracking the frame. If in doubt I'd phone up the manufacturer of the frame and ask!

Old thread.. But here's how I fixed it on my bike... Cut an old inner tube into strips that wrap around the rails. Wrap them around the rails and tighten down.
