The breathing pipeline connector is used for being detachably connected with an air conveying pipeline and comprises a connector body and an elastic component arranged on the connector body in a sleeving mode, and the connector body and the elastic component are matched to form an airflow channel for fluid circulation; the connector body comprises a pipe body and two first cantilever structures arranged along the pipe body in an aligned mode, each first cantilever structure is provided with a pressing part and a clamping part, the air conveying pipeline is provided with a matching part matched with the clamping part, the breathing pipeline connector is connected with the air conveying pipeline through clamping matching of the clamping parts and the matching parts, and the pressing parts are connected with the pipe body. The pressing part can deflect relative to the pipe body under the action of external force so as to drive the clamping part and the matching part to be unlocked. Due to the fact that the two first cantilever structures are arranged along the pipe body in the aligned mode, a double-finger pressing area conforming to ergonomics is formed, pressing on the pressing part can be achieved through natural kneading of the thumb and the index finger, and therefore the pressing part is driven by one hand to move so as to achieve unlocking of the connector and the gas conveying pipeline.
