Is that not the handle you pull to slide forwards/ backwards?

Looks similar but no, I thought it could be the type of seat belt holder that 2 door mercs have to bring the seat belt forward but it’s not that either, my W203 couple had them. This has been found in an 06 A class 2 door

Does it not clip onto the seat fore and aft release handle?
