If yours are like mine, look for a small slot near the top of the plastic retainer. Place a straight blade screwdriver in the slot and pry up a little bit. After it tries to release, push the retainer up from below and it should pop right off. Sorry I don't have any picture because The Silver Otter is over at the shop getting her NEW Dometic installed.
