Reports this week suggested the Rugby Park number one was close to penning a deal with the Ibrox club that would see him join Ally McCoist's side after their transfer embargo ends on September 1.
Bell admits his agent has held discussions with the Irn-Bru Third Division side but was adamant that he has yet to put pen to paper.
And the Scotland keeper admits there is still a chance he could stay with Killie in the Clydesdale Bank Premier League or even join another as-yet-unnamed suitor.
The 26-year-old told Press Association Sport: "There has been discussions but I haven't signed anything with anyone yet.
"My only focus right now is to be with Kilmarnock until the end of the season and do my best for them.
"I'm still in talks with Kilmarnock too and, while I know there's been a lot in the press about it, nothing has been done.
"My agent has spoken to a number of different clubs. It's not just one club.
"He's been talking to Kilmarnock for the last two or three months, and there's been three or four other clubs who have contacted him to ask about my situation.
"I feel it's only right that as a player I look at all avenues but nothing has been agreed yet.
"I'm injured at the minute and that is what I'm concentrating on."
A hip injury means Bell will miss Kilmarnock's trip to Inverness on Wednesday alongside injured team-mates Rory McKeown and Cillian Sheridan.
With those three first-team regulars unavailable, boss Kenny Shiels will once again put his faith in youngsters such as Ross Barbour, Mark O'Hara and William Gros having lost three players in the January transfer window.
He did add to his group with the free-transfer arrivals of Celtic youngster Rabiu Ibrahim and Sammy Clingan from Doncaster Reserves but resisted the urge to add loan signings to his group, opting instead to give the youngsters a chance.
Shiels said: "We want to be a club who grows our own players and doesn't bring in loan players, because that is a real football club.
"I don't blame clubs for going down the loan route but what we are doing is impeccable. We're doing it the right way.
"Not bringing in loan players massively disadvantages you but that's the way we are going."
