A slide rail assembly includes first and second rails, a stop, a first engaging member, and a first releasing member. The second rail can be displaced between a retracted position and an extended position with respect to the first rail. The stop is located at the first rail. The first engaging member, movably connected to the second rail, is at an engaged position with respect to the stop when the second rail is at the retracted position with respect to the first rail. The first releasing member is configured to operatively drive the first engaging member away from the engaged position so that the second rail can be displaced from the retracted position toward the extended position with respect to the first rail.
