The present invention relates to an improved structure of a socket which ensures a secured retention of a plug connected to the socket. The socket comprises a set of swinging rods being pivotally mounted at the central section of the bottom edge of the rod. A press-hold member enclosed a spring is disposed in between the space formed by the rods and is used to appropriately press and hold the pivotally connected bottoms edge of the rods such that the swinging rods can be opened (extended) or closed (retracted) about the pivoted point. When the prongs of a plug are inserted into the socket and pressed at the press and hold member, the bottom edge of the swinging rods which curved upward into a horizontal flat position are pressed. At this instance, the protrusion on the top end of the rods will be inserted into the hole provided at the end of the prongs as a result of forward movement of the swinging rods. Thus the prongs will not be dislocated when the plug is connected to the socket.
