Scotty Marine's Paddle Leash packs a lot of good features into one product. First of all, there is a risk of getting tangled in one's paddle tether, so the shorter tether cord the better. Yet the tether cord needs to be long enough to let you move through all your paddle stroke ranges of motion including rolling. So a stretchy cord is better than a rope tether, and a coiled cord stretches even more than a bungee cord. The Scotty Marine Paddle Leash combines a coil cord with clips at both ends so you can disconnect it at either end -- another safety feature in case you get fouled up in it. The Paddle Leash comes with two figure "8" loops to put on your paddle and spare paddle. With these loops in place it is quick and easy to clip the tether to your paddles. When not using the paddle tether, you can clip both ends to the bungees in front of your cockpit so the tether will always be ready when needed.
Note there are situations when it is dangerous to tether your paddle, and other times when tethers can come unclipped or break accidently. So never rely on a paddle tether as your first line of defense -- use it as a back-up in case you drop your paddle by mistake. Carry a spare paddle and practice wet exits and rescues until you can do them without letting go of your paddle. Don't tether your paddle in surf or fast, swirly currents.
