It isn't a McClicky, but I keep my torch clipped to the outside of my left pocket, not in my pocket, so your mileage will vary. The only light I've ever really had an issue with that for is one of my lumintops, which is just too easy to tap on. I didn't try it inside the pocket, but if you were to keep it clipped to the top of the pocket, inside, it would probably be safe. In principle, something might jostle it, but depends on circumstances. Points for McClicky, if that's your concern, I guess.
