A band clip includes a body, a band integral with the body, and a clip that is attached to the body. The body has a vertical plate with a band insertion hole and a horizontal plate with a clip attachment hole. The band extends from the vertical plate. Locking holes penetrate the band at intervals. The clip includes a shaft that is fit into the clip attachment hole of the body, a wing on one end of the shaft, a band locking claw at another end of the shaft, and a body locking claw on an intermediate portion of the shaft. The band is wrapped around a group of wires and inserted into the band insertion hole. The band locking claw of the clip is inserted into and locked to a band locking hole, and the body locking claw contacts the surface of the body.
