AWG20 10PCS 5050 5630 LED Flexible Light Strip to Power Clip on Connector and DC Jack 5.5x2.1mm Cable 2 Pins 10mm Wide Strip to Strip Jumper Wire Solderless

Works great to be able to do multiple jobs. I like how easy it is to use. You can use with many brands as long as it's the same connection points and same width.

Used these for several project boxes. They had a nice tight grip. They are designed for 10mm strips, but they still worked for my 8mm strips.

I really like these LED connectors. No instructions, but not too difficult to figure out. The connection is quite solid if used correctly.

having tried several different connector styles, I found these to be the most reliable. None of the connectors that I tried are "lock tight" but these held the best without resorting to a soldering iron. i found some connectors styles worse than useless (because I had to live thru being annoyed at trying to make them work) but these at least will grip the tape to be snug. You are not going to tarzan swing on them but they do a half decent job gripping the tape. The facts are, this is a "friction" connection, not a "piercing" one.

Very simple design, and works well.
