What's this connection and how do I detach it

[mattjones]

I've finally got round to spraying up the inlet etc on my 182 and have come across this connection

Does anyone know what it's called and how to get it out?

Any help would be much appreciated

Thanks

Matt

At the base there is a tab you push in, push the tab in while pulling away from teh manifold and it will come off pretty easy.
