An electrical connector (1) comprises an insulative housing (3) with a front surface (302) and a rear surface (303) and a locker (4). The insulative housing defines a plurality of passageways (305) and channels (308). A plurality of contacts (6, 7) is secured in the passageways and channels. First, second and third projections (34, 36, 38) are configured in rows and parallel to the front and rear surfaces. The locker comprises an inner surface (44) being attached to the housing and a plurality of grooves (400, 402) depressed from the inner surface. Each groove defines a protrusion (404, 407). The protrusions are retained between the first and second rows of projections (34, 36) before the connector is mounted to a PCB (2), and moved to securely engage with the third row of projections (38) after the connector is mounted to the printed circuit board.
