I'm trying to replace a circuit board on a rangehood, but can't work out how to remove a circular clip.
In the picture below, I'd like to know:
1. What is the name of the type of clip in the top-left?
2. How can I remove it with common tools? (I don't have any specialist clip removal tools.)
The clip seems to be designed to easily push on, but not to easily come off.
I have removed these occasionally in the past, but this one is especially resistant.
