Help please! Fuel tank pump connector S350 diesel

[MarkFL]

I have a fault on my fuel level indication and I’m trying to check my fuel sender but can’t see how to easily release the green plastic clips on the fuel pump connectors. I’ve tried obvious stuff but they don’t release freely and I don’t want to risk breaking them
Any tips greatly appreciated.

With some of those type of connectors the "green" part pushes inward to release the fitting , once the pipe is refitted the green part will just lock it into position.

Brilliant, thanks. I looked of course but didn't find this video
