A wireline lubricator and a connector includes a first part with a first seal portion and a first throughgoing passage for receiving a part of a wireline, and a second part with a second seal portion and a second throughgoing passage for receiving a part of a wireline. The first part is pivotally connected to the second part such that the connector is capable of assuming a first configuration and a second configuration. The second configuration and the first and second throughgoing passage are aligned. The first and second seal portion engage each other to provide a sealed wireline passage defined by the aligned first and second throughgoing passage.
