A communication plug comprises a cylindrical housing and a fastening ring. The cylindrical housing is provided therein with a space for receiving therein a connection guide wire and an insulator. The cylindrical housing is fitted into the fastening ring which has an inner threaded segment for fastening with a jack of a main machine. The fastening ring is further provided with a retaining ring having a plurality of indentations located in the circumference thereof. The cylindrical housing has a front end provided thereon with a rear cylindrical segment and further has a recessed segment located between the flange and the rear cylindrical segment. One end of the rear cylindrical segment, which is adjacent to the recessed segment, has a diameter greater than a diameter of another end of the rear cylindrical segment. The retaining ring has an inner diameter smaller than the largest diameter of the rear cylindrical segment. The retaining ring can be forced to deform so as to permit the fastening ring to be fitted securely over the recessed segment of the cylindrical housing.
