An electrical connector includes an insulative housing, a plurality of first contacts arranged in a side-by-side manner, and a resilient contact retained in the housing. The housing defines a mating face, a blocking face and a mating cavity disposed between the mating face and the blocking face. Each first contact defines a first contacting portion projecting into the mating cavity. The resilient contact defines a blocking piece abutting against the blocking face, a retaining leg extending out of the mating cavity, and latching arms extending into the mating cavity from the blocking piece. The latching arms can be easily released from a mating connector so as to realize a better retaining effect.
