Header push-pin pigtails

For decades I've had a drawer full of little rectangular female "push-pin-type" pigtails that I could slide over PCB DIP pins. Never paid much attention to it. But alas, now that cupboard is bare. None left.

Does anyone know a source for these things in modest quantity. And what, exactly, are these called? My usually-productive Google searches aren't finding much, except 1K+ lots with a million options at places like Digi-Key.

I just need ones to break out the internal DIP headers on the Due and Mega (large and small diameter) to allow me to easily disconnect/reconnect wires to them.

Thanks

what happens when you google dupont connector ?

the expensive crimpers will last you a lifetime. the cheap ones will aggravate you.

Perfect, thanks so much! The word I needed.

Got a picture? Like one of these maybe?

Or pins to slide onto square posts?
