An electrical connector includes a base, terminals and a cover. The base is formed with terminal slots for receiving the terminals, and one connection portion having an open end into which a flexible circuit interface may be inserted. A pushing plate is formed above the connection portion. A first elastic arm is formed with a connection point extending to the connection portion. The terminals are electrically connected to the inserted interface. The metal cover has a handle and a pressing plate. Two sides of the cover are formed with projecting pivoting portions pivoting onto two sides of the connection portion. The pressing plate may extend into the connection portion to tightly press against the pushing plate and the interface when the cover is rotated downwards. The pressing plate is exposed out of the connection portion to make the pushing plate and the interface loose when the cover is lifted upwards.
