Phone lcd connector doesnt "click" or keeps getting lose

Hello,

Im replacing the display from my samsung S8.

But for some reason the “connector” wont stay connected it keeps comming lose..

Since i dont know the original name of the connector i cant find anything online..

Google image search links me to chinese site’s.

How can i fix this connector so it stays connected?

I tried cleaning it and all pins are like they should be.
