If I remember right...it's two separate pieces. The metal socket and a hard plastic sleeve. The sleeve goes in first then the metal socket slides in and pushes the little 'ears' out to lock the whole thing in place against the backside of the fascia, at the same time little clips also grip the socket to hold it in place.

To remove you have to insert a tool (I used a small flathead screwdriver) in the socket (carefully...to avoid the 12v handshake...lol). There should be little square holes on inside of the socket where the clips from sleeve grip the socket. Push the clips back through the holes and the socket should start to pop out of the sleeve. Once out the sleeve comes right out as well.
