I've recently been considering getting a Prince Albert, I'd love to have one but my keyholder is completely against any sort of body modification. So, I experimented with trying to make myself something like a teatherspout device, without much success, my main problem being getting the right materials to make the device from. Then one day I was doing something very vanilla (filing my tax return!) and I had a eureka moment. The retainer on the paper file I was using was exactly the right shape and size. A picture is worth a thousand words, so I've made the image below. The device that I've created seems quite safe and secure. It's very easy to insert, each of the two retainers is inserted separately, the thinness of the wire allowing easy insertion. When the two retainers are inserted and brought together and locked, the two curved ends of the retainers form the shape of a mushroom, so being impossible to withdraw while they stay locked together. It is easy to custom fit for any individual. First the end loop should be sized as large as will still easily enter the urethra, there is no need for any stretching or discomfort. Then the angle of the end bend in the loop is increased until it is again as big an angle as remains a comfortable fit when the two parts are brought together. The only problem with my initial device is that it is chromed steel, the chrome coating would be a risk if it flakes off. A better material would be to use some food grade stainless steel wire, which should be easily available to source from catering supplies. Another improvement would be to shorten the device, it only needs to be a inch or two long, and the external ends could be made to interlock so making it firmer when locked. An alternative material could be plastic, two similar shapes made with plastic would be light in weight but just as secure.
