How do i undo this clip - front seat removal

[StealthClio]

Tried to take out the front seats today, and followed the haynes manuel, but cant see how to undo this clip under the drivers seat. theres one under the passenger too. i think it is something to do with the airbag or pressure sensor.

thanks

Pull up the red bit I think.

from which way? in the last pic, does the left side pull up or the right?
