A fastening mechanism formed on a rear of a box-shaped communication device includes upper and lower openings, and upper and lower latches each extended from an edge of the opening and substantially covered the opening, the latch having a hole therethrough. Inserting either bar projected from a member into the hole and lifting the communication device to flexibly deform the latches will secure the communication device to the member. There are further provided two positioning blocks formed on an inner surface of the communication device abutted two upper corners of the upper latch, another two positioning blocks formed on the inner surface of the communication device abutted two lower corners of the lower latch, and two lateral grooves formed within the communication device for permitting the positioning blocks to urge thereon.
