In order to provide watertight properties between a spring socket (1) and a release socket (2) for a plug of a push-pull connector, a bellows expansion joint (5) is provided between the spring and release sockets. When the two sockets are spaced apart, the bellows expansion joint is in the rest (non-stressed) position. When the release socket is driven closer to the spring socket, a stress is exerted on the bellows expansion joint (6, 7). This helps to force back the release socket. By this structure, improvements are shown in the vibration resistance and, at the same time, in the watertightness of the plug of a push-pull connector.
