A fastening device includes an assembling portion, a fastener, at least one flexible element, and a key. The assembling portion has an operational hole, a first plugging hole, a through hole, and a second plugging hole. The fastener is located on the outside surface of the assembling portion, and includes an opening hole that corresponds to the operational hole, at least one first flexible arm is positioned in the first plugging hole, at least one second flexible arm is positioned in the second plugging hole, and at least one short rod passes through the through hole. The flexible element is located between the assembling portion and the fastener. The key is located on the outside surface of the fastener and extends into the operational hole for controlling the relative movement between the fastener and the assembling portion so that the short rod fastens or withdraws the object.
