Thanks for reply it’s a meriva b se 2012 and it’s meant to have three on front door but I only have two and one seems to have bent so need another 2. I can take door panel off again and take pic if needed it looks like this one
These black trim fasteners have a metal spring clip fitted on them which holds them firmly in place on the bodywork. The black plastic part is used to slide onto trim panels so they can be mounted securely. These clips are used on many different Vauxhall
Actually they don't clip onto the door card, they clip onto the top of the door and the door card then hangs off part of the clip, the rubber window seal is then held onto the metal clips by way of the barbs.
