An electrical connector includes an insulative housing and a number of conductive contacts received in the insulative housing. Each conductive contact is substantially located in a main surface and includes a contacting portion extending beyond the front wall of the insulative housing, an intermediate portion extending rearward from the contacting portion and received in the insulative housing, and a termination portion bending vertically from the intermediate portion. The intermediate portion is torn to form at least an interfering means which extending away from the main surface to interferentially engage with the insulative housing for retaining the conductive contact in the insulative housing reliably.
