Field of the Invention [0002] The present invention relates to fastening devices and more particularly to an improved device for fastening a card on the motherboard of a computer. [0003] 2. Description of Related Art [0004] Conventionally, a card is added to a computer for providing additional functions. The size of card is reduced gradually as the development of miniature electronic products. For example, a card is disposed laterally in a notebook complying with mini PCI (Peripheral Component Interconnect). That is, holes of the connector on the motherboard are disposed laterally. A card is thus disposed laterally on the motherboard after fastening at the connector. As an end, the occupied height is much reduced. Also, fastening devices are provided on the motherboard for holding the card stably in addition to the snapping coupling force of the connector exerted on the card. Unfortunately, such fastening devices suffered from several disadvantages such as complicated components, difficult installation, etc. Thus, the need for improvement still exists. SUMMARY OF THE INVENTION [0005] It is an object of the present invention to provide a device for fastening a card on the motherboard of a computer in an easy, simple installation procedure.
