Mercedes Ponton wire clip. 

Used in the Ponton's trunk, away from the trunk's opening.

You may have to bend the tab back down.

From a 190b.

The last photograph shows the two kinds of wiring clamps used in the trunk.
I have both kinds listed at this time.

Good condition.  

Price is for one.

Most things ship the same or the next day.
