Mick McCarthy’s side have the option to make the deal permanent at the end of the season.
He told the club’s official website: “Adlene is an all-round midfield player who is very mobile and can get up and down the pitch.
“Technically he is also very good and has the physical characteristics to be able to cope with the Premier League.
“He’s another player who has been scouted abroad by Taff (Ian Evans) and I’m delighted we’ve been able to bring him in.”
