"I am very pleased and happy to be given the chance by Peter Reid and the rest of the club to play some first team football and hopefully I can repay everyone.
"Coventry is a big club, with a great history and a great manager. They may not be getting the right results at the moment but things will turn round with the football they play."
Having left Arsenal Academy,Ricketts moved to North London rivals Tottenham and scored for Spurs in their 3-0 League Cup win at Highfield Road last season.
Ricketts added: "It was a great moment for me but I don't want that to carry on and I don't want the fans to hold that against me.
"But yeah, that was my first goal and it was a special moment. "I have settled in quickly because I know Stephen Hughes, Tim Sherwood, Craig Pead and Graham Barrett. I played with Hughesy at Arsenal now and again, with Tim Sherwood at Spurs now and again. I know Graham well, we won the Youth Cup together.
"Leicester are going to be committed and it's going to be a hard game, but I think we'll win. All the boys look comfortable and excited so hopefully we'll win the game and everyone can be happy in Coventry."
