An electrical connector (100), mounted on a printed circuit board (PCB) (1), includes an insulative housing (2), a load plate (3) shielding over the insulative housing, an elastic piece (51) and a screwing element (50). The insulative housing has a plurality of electrical contacts (22) received therein. The load plate forms a tongue portion (30) at an edge thereof. The tongue portion defines at least one hole (31, 32) therein. The elastic piece forms a base portion (510) with a pair of inner hook portions (512) and a pair of outer hook portions (513) thereon. The outer hook portions and the inner hook portions go through the at least one hole and respectively and correspondingly engage with the tongue portion of the load plate and the screwing element.
