    wherein when the pull tab is pulled rearwards, the latch releasing portions push the sloping portions, the sloping portions deflect outwardly to motivate the second claws to move outwardly accordingly whereby a latch of the second claws with the complementary connector is released;

    wherein the each latch spring defines a cutout in the sloping portion, the latch releasing portion having a protrusion extending into the cutout from an inner face to an outer face of the sloping portion, so that the latch releasing portion contacts with the inner face of the sloping portion of the latch spring;

    wherein the protrusion protrudes outwardly from an outside face of the latch releasing portion;

    wherein the latch releasing portion has upper and lower tip ends, the cover and the base each defines a groove receiving the upper and lower tip ends of the latch releasing portion therein, the tip ends sliding rearwards in the grooves when the pull tab is pulled rearwards;
