Door flyscreen, plastic whatsit. !!

[TUCANO]

Closing the rear door of my van last night l noticed the flyscreen mounting on the door was loose so have it a hefty thump.
The offending piece of snapped plastic then fell to the floor and the mounting became looser
I can't see how the piece is supposed to fit and don't want to try to remove the mounting in case l snap the other plastic whatsit.
So, has anyone an idea of what this piece is called please and also how to remove the screen.
Many thanks.

Many thanks for that, did you find it easy enough to remove the screen.

I used a broad plastic 90-degree car trim removal tool to gently ease the flyscreen away from the surrounding wall.
The flyscreen frame is only held in place by friction, and mine only had the clips down each side of the frame.
I broke an extra clip as I had not realised that a screw for a door security lock had gone through one clip locking it to the wall .
