As Dan says, those clips need to be in the fork and the bearing - there are small holes on each, on each side to receive the clip.
Do the least accessible side clip first, put the bent end of clip in back of fork then rotate bearing to get the straight end in the bearing hole. Then on the other side, rotate bearing into position, put the straight end in first into the bearing hole, then push the bent end back behind the fork and into the hole there.
