Note that this is a "right angle" coaxial connector. The metal cube is a part of the connector and stays with the cable. It is not a part of the airpor card. Also, I found two clear plastic blocks in front of the airport card, a smaller one near the connector and a larger one on the other side. Possibly these are to keep the cable from vibrating and flexing during, say, a truck ride. Don't lose these.
