The invention provides a dirt suction connector, and relates to the technical field of dirt suction, in particular to a dirt suction connector. According to the scheme, the dirt suction connector comprises a first connector body, a second connector body and a breaking part; a breaking piece is mounted on the inner side wall of the first connector, and a supporting part extending inwards is arranged on the inner side wall of the first connector; the outer side wall of the second connector is provided with a clamping part extending outwards, and the clamping part is located between the breaking piece and the supporting part. When the first connector and the second connector move reversely, the clamping part can break off the breaking piece, and the first connector is separated from the second connector. The sewage suction pipe can be automatically disconnected from the sewage outlet when a train is departed, and potential safety hazards caused by the fact that the train drags the sewage suction pipe to move are avoided.
