/diy/ - Do It Yourself

I got some driverless led cobs and I need to get them wired up. I want to make a power cord that I can add or remove lights from connectors wired in parallel along the length. It needs to be a polar two wire connector that can handle 120v so I was thinking something like pic related would be a good option, but I don't think you can buy just the ends for them. What kind of connectors would be best for this? Is there an existing product like this that isn't crazy expensive?
