Stephen Hughes fired over the Wolves crossbar, while Carl Cort and George Ndah both sent chances wide for the home side in the first half.
Joey Gudjonsson struck a left-footed effort wide after the break and Nils Eric Johansson had a long-range shot saved by home keeper Michael Oakes.
Leicester boss Craig Levein:
"We have been coming off the pitch recently saying we should have had more shots and more possession.
"We have had to do something else and that was to build a platform and make sure we are hard to beat.
"We have changed the emphasis a bit. We just cancelled each other out and that was probably more my intention."
