A belt connector is provided. The belt connector is configured to electrically connect a conductor of an electrode belt to a male portion of a snap connector electrode connected to a biometric device. The belt connector includes a frame, a fastener, and an engaging member. The frame includes a receiving hole having radial flexibility. The receiving hole is configured to receive and fasten the frame to a protrusion of the male portion of the snap connector electrode. The fastener is configured to fasten the frame to a first end of the electrode belt. The engaging member is adjacent to the receiving hole and engages the conductor of the electrode belt by the conductor passing through the receiving hole. When the male portion of the snap connector electrode penetrates the receiving hole, the conductor is forced into contact with a lateral surface of the male portion of the snap connector electrode.
