The 30-year-old has played 12 times for Orient since joining in October.
"There were one or two alternative options that came up but having been here for three months and got a feel for the place, I am happy to be staying," he told the club website.
Orient, who are 21st in League Two, face Mansfield on Saturday.

The alleged spying by the National Security Agency (NSA) "must be explained and more importantly new trust must be built up for the future", she told German MPs.
The allegations dominated the news during an EU summit last month.
Ms Merkel said the NSA affair was putting EU-US trade talks to the test.
She also said Germany's relations with the US "are of paramount importance".
The German government has said it is keen to hear directly from the fugitive NSA leaker Edward Snowden about the agency's collection of phone and internet data.
But Germany says it cannot offer him asylum because he would have to make his application on German soil.
According to his leaks, the NSA targeted communications among Washington's Western allies, including Ms Merkel's mobile phone and EU offices.
"The accusations are grave," Ms Merkel said in her statement on Monday. She did not comment specifically on the alleged bugging of her phone.
The Bundestag - Germany's lower house - is holding a special debate on the NSA spying allegations.
The scale of NSA surveillance in Germany is not clear, and last month Germany sent some senior officials to Washington to find out more.
German media report that the German secret services exchange intelligence with their US counterparts.
But recently the British newspaper the Independent, citing leaks from Mr Snowden, said the UK spy agency GCHQ had tapped into communications using a listening post on the roof of the British embassy in Berlin.
Mr Snowden, 30, fled to Russia in June after leaking details of far-reaching US espionage. He has temporary asylum, allowing him to live in Russia, until July 2014.

The home side had an Alfredo Morelos goal disallowed and saw Bruno Alves' header cleared off the line.
Hearts struck the crossbar through John Souttar, but Caixinha was positive about Rangers' display.
"One team dominated from the beginning to the end," Caixinha told Rangers TV.
"I'm disappointed with the result, of course, which is the most important thing, but I really liked the team.
"[Hearts] tried to create something at the beginning of the game to delay our pace, they did it, but we finish the first half completely dominating, with some very good chances to score, which we could not do.
"I'm happy with the way they fought until the end.
"You cannot control this type of situation but what you can control is what the boys did, the effort, the hard work, the teamwork, not allowing the opponent to play and always looking to play our game."
Rangers have now dropped five points in consecutive home games - against Hearts and then Hibs - as Caixinha integrates the nine new players who arrived during the summer.
The Ibrox manager insists his side are playing well, but failing to convert chances and not maintaining a high enough intensity to their play.
"The only point I need to refer to is the pace of the passes needs to be higher, a higher tempo of passing and moving," Caixinha said.
"Regarding to the overall and especially the ending position on attack, we were very good.
"I don't remember one single transition from the opponent, or one single time where they could get the confidence to try to beat our last line.
"We did everything we could to win the game, we had the chances to win it but we could not do it.
"The timing and the tempo of the passes, the way we move in attack, yes definitely we need to improve that - that's all I take because the boys leave everything, they play the way we want them to play. We created chances and avoided the opponent having transitions, but we didn't score goals.
"We are controlling the moments of the game but should be more aggressive in the last third. To win you need to score goals, and we didn't do that."
Leyton Orient midfielder Michael Collins has signed a new contract which will keep him with the League Two club until the end of the season.
