With the hosts tiring, Barca finally worked an opening when Lionel Messi fed Carles Puyol on the right of the area and the defender crossed low for Seydou Keita to slot in from close range after 72 minutes.
The tireless Mali midfielder, who scored a hat-trick against Real Zaragoza last weekend, has now scored six goals in La Liga this season.
Barca appeared to be cruising to victory but in the last move of the game Osasuna's Javier Camunas crossed from the left and Pique gifted the home side a well-deserved point with an own goal.
