and
guide grooves connected to the corresponding leg guide grooves;
wherein the slide cover comprises at least two pieces and being installed on the guide holder so that the pieces of the slide cover are moved radially outward with respect to the through hole by an insertion force of the terminal, each piece of said slide cover comprising:
a body;
a leg formed on the lower surface of the body and guided by the leg guide groove of the guide holder;
a cover piece formed on the upper surface of the body to close the jack hole of the housing when the pieces of the slide cover are constricted radially inward by the elastic retainer;
and
a guide section formed on the lower surface of the leg and having a cross sectional area greater than that of the leg, thereby being guided by the guide groove of the guide holder;
