The receptacle connector comprises an insulative housing ( 21 ) and a plurality of first terminals ( 24 ) received in the housing. The housing comprises a base portion ( 211 ) and a mating portion ( 212 ) extending from the base portion ( 211 ). The mating portion ( 212 ) comprises a top wall, a bottom wall and a pair of side walls connecting with the top and the bottom walls and defines a tongue ( 26 ) therein. A lateral side of tongue connects with one of the side walls, and another side of the tongue is spaced with the other side wall where a recess ( 262 ) is formed. The plug connector comprises an insulative housing ( 11 ) and a plurality of second terminals ( 14 ) received in the insulative housing. The housing comprises a base portion ( 111 ) and a pair of parallel tongues ( 113 ) extending from the base portion. A rib ( 114 ) is formed to connects the two tongues. The rib is received in the recess when the two connectors engaged with each other to avoid mis-mating.
