The swivel mechanism is formed from two pieces of tubing held together at ends thereof, said two pieces of tubing being rotatable with respect to each other. The tubes forming the swivel mechanism may be solid plastic or hollow tubing, and they are connected to the outer tube using, e.g., rivets, screws, staples.
