200: Rear Roof Bars Mounting Point Access Flaps?

Does anyone know if you can pop these fellas off completely or are they part for the trim panel they go into. I left mine on open because the rubber blocks that the bars sit on had enough room inside the hollow space in them but it's still managed to snap the flaps off.
Basically I just need to know if I can get the little flaps separately from a bog standard Clio and get them painted or do I need to buy that complete strip that goes along the back half of the roof on each side? It looked like you could take the flaps of by pushing down a little leg underneath it but I didn't have the balls as it was part of the panel which is obviously more expensive to replace if I break that.
