Abstract: A connector for connecting electrical conductors and including first and second conductor-containing bodies configured to sealingly connect the conductors when the first and second body are matingly joined. A passageway is formed to accept a pin when the first and second body are matingly joined so that the pin, which is a different color than the first and second body, is readily observable in position to confirm that the first and retains the first and second body in mating engagement and so that the pin, which is a different second body are matingly joined.
