A socket member comprises a main body, a resilient bent wire and a seating element for enclosing the resilient bent wire in the main body. At least two straight portions of the resilient wire spaced apart in parallel by a desired distance are disposed in a recessed portion of the main body for receiving the head of a stud member so as to retain the stud head in engaged position in clamping contact therewith. The socket member has a seating element which is provided with walls defining an annular inclined groove and secured within the body in spaced relation to the bent wires by abutment with the stud receiving portion and the outer walls of the body, so that said seating element receives and effects the upsetting of the prongs of a pronged attaching member.
