I’ve taped and tied a lot of electrical cords together to keep them from pulling apart during use. Problem is, tape is pretty inconvenient when I need to take the cords apart. Tying the cords with a knot inevitably results in snagging the cord on something.
To remedy both conditions, I use a flexible rubber plumbing coupling. I use one that has about a 1-1/4-in. I. D. It’s about 5 in. long. I simply slide the coupling over the ends of the cords, as shown in the drawing, and tighten the hose clamps enough to keep them from parting. This more streamlined shape seldom snags, yet I can easily separate the cords if needed.
