Tottenham striker Keane joined his boyhood idols in a transfer deadline day move at the beginning of last month in a bid to rescue their ailing season. Amid rumours Celtic will approach Spurs over extending his loan move into next season, Redknapp has moved to end any hope of that happening.
"I don't see us loaning Robbie out again," the Tottenham boss said in the Scottish Sun.
"We paid a lot of money for him. So it's not something I see happening. It would obviously be up to the chairman but I couldn't see it being a possibility."
He added: "I certainly would not want it to be happening.
"Robbie's only on loan until the end of this season as far as we're concerned.
"We want him back so in my mind there's no way of another loan deal."
