Swansea City chairman Huw Jenkins was pleased with their late transfer business.
“Andre is a player we know very well and the manager is delighted to welcome him into the squad," said Jenkins.
“Aside from his experience and the fact he has been here before, his ability to play in different positions is a big help to Carlos.
“He will provide the options needed in certain games.
“With the way Jordan is playing, it will be interesting to see how his bond with his brother can develop in the remaining 13 league games.
“His character and personality is something every club needs, and he will help us a lot.
He added: “Andy is well known to everyone in football. He has been a good servant to Leicester and he will add quality and experience to our squad.
“The aim is for Andy to come here and compete for a starting role and push us forward."
