An electrical connector assembly comprising:

• a cable end connector including:
• a first insulative housing with a plurality of first contacts therein;
• a cable including a plurality of conductors connected to the corresponding first contacts, respectively;
• a metallic locking member attached to the first housing with at least a fulcrum at a rear end, a latch portion at a front end and a main pressing section between said fulcrum and said latch portion;
• an upper wall of the first housing defining a depression receiving the moveable locking member therein;
• and
• a complementary connector adapted to be mounted to a printed circuit board and mate with the cable end connector, said complementary connector including:
• a second insulative housing with a forward mating tongue;
• a plurality of second contacts disposed in the second housing;
• a protection portion spatially located above the mating tongue in a vertical direction with an engaging opening therein;
• wherein
• when the cable end connector and the complementary connector are mated with each other, the first contacts and the second contacts are mechanically and electrically engaged with each other and the upper wall of the cable end connector is received between the mating tongue and the protection portion of the complementary connector under a condition that the latch portion of the locking member is latchably engaged in the engaging opening.
