There are pipes made for mountain climbing which have a ring on them for attaching to a carabiner. This is not one of them. But follow Cosmic's advice and put it on a string and fashion yourself a necklace. You could put a loop of string around the tenon like at pipe shows, but you could have that sucker around your neck. Boom. Just make sure the string is short enough that it can't reach the ground or you'll look like an idiot when you drop your pipe.
