    two grooves on opposing sides of said tubular nose portion of said first core, said grooves forming a narrow end portion, each of said grooves extending from said end toward said base portion and terminating in a shoulder;

    a second core including a base portion and two parallel and generally tubular fingers extending from said base portion to an end;

    an open channel between said fingers; and

    said first core and said second core engaged together in such a manner that said narrow end portion of said first core is fully extended into said channel on said second core and said end of said fingers of said second core engage said shoulders on said first core,whereby said engaged cores are capable of being inserted in the cavity of a mold that is capable of being closed and having molten metal or plastic admitted therein into said cavity thereby producing said flash free one-piece connector body.
