15. The electrical connector assembly according to claim 14 , wherein the socket further comprises a closure movable to selectively close the interior of the receptacle, and the catch comprises a finger depending from the closure.

16. The electrical connector assembly according to claim 15 , wherein the key comprises a proximal end configured for abutting contact with the finger to retain the plug in the socket and compress the resilient seal against the proximal face of the receptacle wall.

17. The plug according to claim 16 , wherein a distance between the finger and the proximal face of the receptacle wall is less than a distance between the key proximal end and a distal end of the resilient seal when the resilient seal is uncompressed.

18. The plug according to claim 12 , wherein the resilient seal extends distally beyond the distal end of the body.

19. The plug according to claim 18 , wherein the resilient seal comprises a peripheral lip.

20. The plug according to claim 12 , wherein the socket and the plug each comprise seven of the electrical terminals.

21. The plug according to claim 12 , wherein the resilient seal is made from a polymeric material.

22. The plug according to claim 21 , wherein the polymeric material comprises polyvinyl chloride.

23. The plug according to claim 12 , wherein the body is overlain by an outer cover having a differing rigidity.

24. The plug according to claim 23 , wherein the resilient seal is uninterruptedly formed with the body.

25. The plug according to claim 24 , wherein the resilient seal is configured to be compressed between the outer cover and the proximal face of the receptacle wall when the catch mates with the catch receiver.

26. An electrical connector assembly comprising:

a socket comprising:

a receptacle defining a cavity that terminates at an immovable wall having a proximal face; and

at least one socket electrical terminal extending through the immovable wall into the receptacle and accessible therethrough;

a plug comprising:

a body configured for selective retention within the cavity of the receptacle, and having a distal end terminating in an immovable face;

at least one plug electrical terminal carried by the body and accessible through the immovable face, and configured for coupling with the at least one socket electrical terminal; and

a compressible ring-like peripheral seal located at the distal end of the body, and configured to encircle the immovable face;

wherein the coupling of the plug with the socket will compress the peripheral seal against the proximal face.

27. An electrical connector assembly comprising:

a socket comprising:

an open receptacle formed in the socket, defining a cavity that terminates at an immovable wall; and

at least one socket electrical terminal extending through the immovable wall into the receptacle;
