Sorry I don't have a picture, but the towing eye is behind the driver's side foglight cover or blanking plate on UK RHD cars. I don't know if it's the same or opposite side for LHD. But in either case insert a flat blade screwdriver between the straight end of the cover/blank and the lower grille, at about the 1/4 and 3/4 points, there are two clips to lever gently to release it and pull that end out. Then the two locating lugs should just come out of their holes in the round end next to the bumper and it'll come free.
