An electrical connector includes an insulative housing, upper and lower contacts disposed in the housing, a metallic shielding plate, and a metallic shield enclosing the housing. The insulative housing includes a first insulator with a first mating tongue thereof, and a second insulator with a second mating tongue thereof wherein the shielding plate is sandwiched between the first insulator and the second insulator. The shielding plate forms a cutout with side edges in two opposite lateral sides. The second insulator forms a pair of pressing parts extending toward the shielding plate with a hook at the end. When the shielding plate is assembled to the second insulator, the hook engages the side edge of the cutout so as to secure the shielding plate to the second insulator in the vertical direction.
