An electrical connector includes an insulative housing having a mating tongue and a supporting tongue both extending forwardly in a front-to-back direction and spaced from each other in a vertical direction perpendicular to said front-to-back direction. A plurality of contacts is disposed in the housing with corresponding contacting sections exposed upon the mating tongue and corresponding tails retained in the housing. A metallic shield encloses the housing and cooperates with the supporting tongue to commonly define a mating cavity in which the mating tongue extends forwardly. The supporting tongue includes a plurality of cutouts in which a plurality of offset spring tangs of the metallic shield extend with corresponding ends extending into the mating cavity.
