Air line connectors

What are those tiny connectors that Bob uses to connect air hoses together called?

I am not sure exactly which ones you are referring to but I really like these 1/4 turn quick couplers https://sculptingstudio.com/quick-disconnect-coupling/

Guess I can use intravenous tubing.
They come with locks on the ends.

I just use silicone hoses and brass tubing for my pneumatics and hydraulics.
