A locking device for mounting a heat sink ( 50 ) to a heat generating component surrounded by a retention module ( 60 ). The locking device includes a first locking member ( 10 ), a second locking member ( 20 ) and an operating member ( 30 ). The first locking member secures a first side of the heat sink with a first side of the retention module. The second locking member is disposed at a second side of the heat sink opposing to the first side. The operating member is pivotably attached to the second locking member and is capable of acting upon the heat sink to drive the second locking member moving from a released position to a locked position. The operating member has a cam ( 31 ) and a free end. At the locked position, the cam downwardly depresses the heat sink and upwardly pulls the second locking member, and the free end locks at the retention module.
