An exemplary slide rail assembly includes a first rail with a protrusion, a second rail, a releasing member, a pair of push buttons, a first latch member, and a second latch member. The releasing member is slidably attached to the second rail and includes a pair of openings for receiving the buttons, and two angular driving edges. The second rail includes a pair of resilient tabs detachably and respectively engaging with the buttons and the releasing member. The first and second latch members are pivotably attached to the second rail. The first latch member includes a post extending therefrom to be selectively driven by the driving edges of the releasing member. The buttons are actuated to release the releasing member from the resilient tabs and move the releasing member to drive the first latch member and the second latch member to disengage the protrusion of the first rail.
