Abstract: A coaxial cable coupling made up of a plug and a socket. The plug comprises a hollow shell open at its ends, which receives an insulation washer. The insulation washer receives a hollow pin having a cylindrical wall which has a flange on one end and outwardly extending protrusions which receives the washer between them and holds the washer in place. Four indentations in the cylindrical pin extending inwardly grip a conductor and thereby electrically connect the pin to an electrical line. The pin is adapted to be received in a tubular connector on a socket having a hollow shell.
