Or just refrain from forcefully tightening the ring. Gently twist it on until you feel resistance, then stop immediately and leave it there. Unless you believe in ghosts, the ring is not going to spin itself off the lens. I am certain most stuck-on filters are the result of people either dropping their cameras, or applying way too much force attaching the filter! There is no reason to do so unless you want to keep the ring permanently attached.
Not to quibble with others, but I have use the rings with my filters for many years now. It is correct that you should not over tighten them, and I do always have a filter wrench with me. So far, I have not needed to use it. Of course, YMMV.
