Front splitter install question

[DAVESVT2000]

The four half moon clips, what exactly is their function?
I see where they go, but what do they do?

If you’re watching the ford service video on splitter install, it’s at the 2:30 mark.

I believe they hold the 2 outer parts in IIRC

I’m addition to the the screws and clips on each outer piece. Ok, that would make sense. Thanks
