The right-back has made five appearances since joining Fulham in January, and he will now remain in SW6 for the remainder of the 2014/15 campaign.
Fulham boss Kit Symons was keen to extend Jazz Richards’s loan stint at Craven Cottage.
The Swansea City right-back’s initial one-month stay in West London was due to come to an end this week.
But the Championship side were keen on an extension as Richards has impressed in his five appearances to date.
“We’re looking to extend the deal for Jazz Richards. He’s done pretty well for us,” Symons had said.
The talented full back has found himself close to scoring, as well as defending impressively. He became particularly well heard of among the Fulham fans after a spectacular goalline clearance in Fulham's goalless draw with Millwall.
Wales international Richards, 23, came through the ranks at Swansea, having joined the club from rivals Cardiff City as a trainee.
