A connector includes a cage having a plurality of receiving chambers, a separation mechanism including a lower separation plate and an upper separation plate, a radiator disposed between the lower separation plate and the upper separation plate, and an elastic clip mounted on the radiator and elastically holding the radiator in the separation mechanism. The separation mechanism is located between and separates a pair of adjacent receiving chambers of the plurality of receiving chambers in a height direction of the connector. A pair of sides of the elastic clip opposite to each other in a lateral direction of the radiator are fixed between the lower separation plate and the upper separation plate.
