Ripley, who played Jenny in the show, told the Daily Record that people still mention it to her when she is out.
"Cold Feet completely changed my career," she said. "Well, I didn't really have one before.
"People are so nostalgic about the show and as a result I become very nostalgic about it. People used to say, 'Hi Jenny' when they saw me."
Ripley added that she has enjoyed filming the second series of Reggie Perrin with Martin Clunes.
"I've worked with Martin a couple of times," she said. "We've been put together as man and wife before Perrin, so something must work. Maybe because both of us have sticky-out ears! The thing about Martin is that he's the nicest man in showbusiness - and I don't say this about everyone I've worked with. He is exactly what you think he is going to be."
The second series of Reggie Perrin will air on BBC One in the autumn.
