Details of the settlement, including the amount of any damages to be paid by Strauss-Kahn to Diallo, will not be made public, McKeon said at a court hearing Monday, according to US media.
Nafissatou Diallo, the 33-year-old maid, had accused Strauss-Kahn of forcing her to perform oral sex and trying to rape her in May 2011 when she went to clean his hotel room in Manhattan. He said the encounter was consensual.
Strauss-Kahn, 63, was arrested and charged with attempted rape and other crimes, but the charges against him were dropped after New York City prosecutors said Diallo had credibility problems.
He was forced to resign as head of the IMF and abandon his plans to run for president in his native France.
