"It was a vital point for us in the end. When you're 2-1 down with just five minutes to go you're delighted to come away with a point," Redknapp is quoted as saying by BBC Sport.
"We were short in some areas but I thought we showed great character to keep going. It's good for the spirit that we didn't get beat."
QPR return to action next Saturday when they travel to Southampton in the Premier League.
