The molded body also includes a wire support portion having vertically spaced ears for receiving an electric fence wire, and two lock pins may be integrally molded with the body and may be connected to the body by flexible and twistable link portions of the plastics material. One lock pin extends into a horizontal hole within the mounting portion and between adjacent projections on the post, and the other lock pin extends into a vertical hole within the ears of the wire support portion. The body may include an elongated horizontal arm portion which integrally connects the mounting portion to the wire support portion.
