unidentified parts inside door

[Konstantine Bogach]

I took appart driver door to fix a broken wire in the door loom.  I
found two metal things (two wide teeth fork-like, 1/16'' thick)   lying
at the bottom, in both coners. The fact that there 2 of them makes me
doubt  a little  that they were accidently droped there or forgotten.
Neither Bentley nor ETKA shows those parts. Are they missing something?
I don't see where they could fall from.

Thank you for reading this nonesense.
