A wire cover for an electrical connector that defines the direction in which a plurality of wires is led out of the electrical connector comprises a main body having side walls. At least one of the side walls has an interference member receiving recess. An elastic engaging member extends from a lower edge of at least one of the side walls. The elastic engaging member has an elastic tongue member bent upwards from the lower edge such that a gap is formed between the elastic tongue member and the side wall. An interfering member extends from the elastic engaging member and into the interference member receiving recess when the elastic engaging member is flexed. The interfering member substantially covers the gap. An electrical connector engaging protrusion extends from the elastic engaging member and engages the electrical connector.
