Looks like Sean Avery and Hilary Rhoda are skating on smooth ice ... 'cause the former NHL player just filed to have his wife's restraining order against him dropped and seemingly confirmed they're back together.
In a Monday court filing in Los Angeles obtained by TMZ, Avery requested the RO -- set to expire on Sept. 11 -- be terminated ... reasoning "mom and dad have reconciled" and that "Hilary and Sean have been living together for over a year."

You may remember .
