This stainless steel enema tubing clamp, made by Klystra, is incredibly resilient and easy to use. It can be slid over any enema tubing before the nozzle is attached, and stays in place nicely once attached. After that, it is as simple as switching it between the open and closed positions to control the flow of liquid in your enema.
