There is a type of expanding bolt which I beleve is used for anchoring things in concrete. I do not know the exact name of it. It is similar in idea to the expandable plug that you use to secure something to drywall. Perhaps you could locate one of these and modify it a little.
Another possible way to accomplish what you want to do would be with a piece of pre-threaded ready rod, some nuts, washers, and some rubber hose.
