Teardrops n Tiny Travel Trailers

I am looking for the name of the little buttons that fit in a piece of pipe that locks 2 pipes together and makes them adjustable I want get use them on my galley supports but can't google them because I don't know what their called thanks BB

I couldn't fine the name of the detent buttons either but if you need a pair keep an eye out at Goodwill and cannibalize the parts off of a folding walker. I have picked the walkers up as cheap as $5.00 . The parts and some aluminum tubing and just drag out the drill and go for it.

McMaster-Carr calls them "Quick-Release Button Connectors for Telescoping Tubing"

Thanks kc and bob that's really the route I want to go
