What is square cover on front bumper called?

[coolio529]

I lost the small square cover piece which is on the colored part of my front bumper (It was silver like the rest of my car) on the right side. Can someone please tell me what the piece is called so I can order a new one? Thank you!!!!!

It is called a "FLAP, TOWING EYE, PRIMED", It is about $7.00 primed and has to be painted.
