Claim:
A fixing device for fixing an expansion card with a cover plate mounted at an end of the expansion card, the cover plate comprising a tab perpendicularly extending from a first end of the cover plate, the fixing device comprising: a substantially L-shaped frame comprising a board defining an elongated slot to be covered by the cover plate, a plate extending in a substantially perpendicular manner from an end of the board and perpendicular to the elongated slot, and a fixing portion extending in a substantially perpendicular manner from a side of the plate opposite to the board; a fastener extending from the plate of the frame, adjacent to the elongated slot of the board; and a fixing member comprising a sliding portion slidably mounted to the fixing portion and an operation portion extending in a substantially perpendicular manner from the sliding portion, the sliding portion defining an engaging hole to receive the fastener; wherein the fastener is to be engaged with the tab of the cover plate, and the fixing member is operable to slide to sandwich the tab with the plate; wherein the sliding portion forms a protrusion adjacent to the operation portion, a latch extends from a distal end of the sliding portion away from the operation portion; the protrusion is blocked by an outer surface of the fixing portion opposite to the board, in response to the sliding portion being slid to move the operation portion toward the fixing portion, and the latch is blocked by the outer surface of the fixing portion in response to the sliding portion being slid to move the operation portion away from the fixing portion.
