Steele joined the Cobblers on an initial one-month loan deal at the end of February and has made four appearances for the League Two club, keeping clean sheets in the last two games.
Cobblers boss Ian Sampson brought Steele in to replace the injured Chris Dunn and the Middlesbrough youngster has been on the winning side in all four games he has played in.
Steele will now play his part as the Cobblers push for promotion back to League One.
