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.
