The green or white strip should lift, up, away from the black pipe. This releases the catch. Then pull the pipe off the spigot.

Use your finger nail or screw driver to push the white or green "button" inwards to unlock WHILE you pull the tube off the spigot. There is an oring seal on the inside of the connector and it can be a bit tight on the spigot shaft.

This photo is interesting. Is your car in/from the UK? Because the pump/sender has two spigots that means it has an external fuel filter. I have not heard of many UK cars (PETROL Citroen C2,C3s) fitted with external fuel filters. The return line usually goes directly to the tank and not back to the pump. The diesels have two spigots but their senders (it is not a fuel pump) are a pinky-faun colour, this one is white indicating it is indeed petrol.
The other thing is the blob of epoxy (I think) around the outlet spigot. The spigots have a reinforcing metal tube molded into the shaft that actually causes the plastic to, eventually, crack. As this is the outlet from the fuel pump, the crack is exposed to more than 3 bar of pressurized fuel. Consequently you get a small stream of petrol squirting out of the crack!
Hmm an interesting solution to that problem.
