An electrical connector (100) adapted for electrically connecting a chip module to a printed circuit board, includes an insulative housing (30) having a plurality of terminals received therein and a fastening device (90). The fastening device (90) comprises a stiffener (50) surrounding the insulative housing (30), a load plate (60) pivotally assembled to an end of the stiffener (50), and a knob (70) assembled on an opposed end of the stiffener (50) for locking the load plate (60). The knob (70) has a stem (702) rotationally provided with a guiding slot (704) helically defined along the stem (702) such that the tongue (610) of the load plate (60) engaged with the guiding slot (704) can be moved up and down when the knob (70) is rotated clockwise and counterclockwise.
