A fixing device comprises a first locking member, a second locking member and a pair of locking nuts. The first locking member includes a base portion, four engaging posts and a pair of positioning posts. A pair of platforms is formed on lateral ends of the base portion. Each platform forms a locking hole for receiving corresponding locking nut. Rotation of the locking nut is limited by the platform to ensure proper positioning of a cap of the locking nut. The engaging posts equidistantly extend from the base portion, and each engaging post forms a circular neck. Each positioning post downwardly extends from the corresponding platform, and has a hollow body communicating with the receiving hole. A slot is formed in each positioning post. The positioning post has an upper portion defining a hole having a diameter larger than that defined by a lower portion of the positioning post. A subulate portion is formed at a bottom end of each positioning post for engaging with the circuit board.
