Internal sill trim removal Skoda Yeti?

[Easternlight]

I'm fitting a tow bar to my Yeti, and need to run the wiring from the front to back, the Witter instructions show how to remove all the trims except the ones across the door sills inside.
I can't find any screws so they must just be on clips, I've had a good pull at them but no luck and I'm worried that I may break them if pulling the wrong way.
Any one been there /done this?
