Osborne, 25, moved to Ashton Gate at the end of October for a month but will now remain a Robin until January 5, 2014.
The defender has made four full appearances for City since being left on the bench in his first match.
The Robins sit in League One's relegation zone and next travel to high-flying Preston.
