A receptacle comprising: a holding member having a rear portion and a plate-like portion, the plate-like portion extending forward in a front-rear direction from the rear portion, the plate-like portion having a lower surface in an up-down direction perpendicular to the front-rear direction; a plurality of first contacts each of which has a first held portion and a first extending portion, the first held portions being held by the rear portion, the first extending portions extending forward from the first held portions, respectively, each of the first extending portions being provided with a first contact portion, the first contact portions being exposed on the lower surface to be contactable; and a plurality of second contacts each of which has a second held portion and a second extending portion, the second held portions being held by the rear portion, the second extending portions extending forward from the second held portions, respectively, each of the second extending portions being provided with a second contact portion, the second contact portions being exposed on the lower surface to be contactable, the first contact portions being located forward of the second contact portions along the front-rear direction, the second contact portions being grouped into two groups between which the first contact portions being located in a lateral direction perpendicular to both the front-rear direction and the up-down direction, wherein: the receptacle comprises a shell; the shell covers, at least in part, the holding member and includes an upper portion extending along the lateral direction and two side portions extending along the up-down direction; wherein the plate-like portion has a first portion and two second portions; the first portion corresponds to the first extending portions while the second portions correspond to the second extending portions; the first portion extends forward along the front-rear direction beyond the second portions and is sandwiched between the second portions in the lateral direction characterized in that the shell is formed with two first locked portions formed in the upper portion of the shell and two second locked portions formed in the side portions of the shell, respectively; and wherein: the holding member is provided with an abutment portion; the abutment portion is located under the first portion and in front of the rear portion; a front end of the abutment portion is located forward of a front end of the second portion or at a position same as a position of the front end of the second portion; and the second contacts being provided at the second portions, the second contacts therefore being guarded. a holding member having a rear portion and a plate-like portion, the plate-like portion extending forward in a front-rear direction from the rear portion, the plate-like portion having a lower surface in an up-down direction perpendicular to the front-rear direction;
