How to remove clips on doser valve

[Nostalgic]

The white connect on the left looks like push on the left side, but they never seem to play along. It doesn't take much grime to mess things up, and the plastic always seems to be brittle. I've had better luck using a pick on the locking tabs end to spread the tabs and push the clip out from that end. Still easy to break though if they're brittled by heat.
