There is provided a device and method for coded securing of a modular plug in a modular receptacle, in particular an RJ-45 plug in a RJ-45 receptacle, the receptacle comprising a front face defining an aperture and the plug comprising a plug body having dimensions substantially the same as those of the aperture and an elongate latch flexibly attached at a first end towards a front end of the plug body and comprising a release lever at a second end thereof and at least one latch tab positioned between the first end and the second end, the second end of the latch biased normally away from the plug body such that when the front end of the plug is inserted into the aperture into an engaged position the at least one latch tab engages an inside of the front face and is retained therein until the plug is released from the engaged position by depressing the release lever. The device comprises a ring or clip comprising a blocking portion having a width substantially the same as a distance between the release lever and the plug body when in the engaged position and defining an aperture having dimensions substantially the same as those of the receptacle aperture, the ring configured for placement over the plug body, and a coding means incorporated into the ring. When the plug is in the engaged position the ring is installed around the plug body flush against the front face with the blocking portion positioned between the release lever and the plug body, thereby preventing the release lever from being depressed sufficiently to release the plug from the receptacle.
