Referring to FIG. 2B, an insertion groove 175 may be formed on the width-directional surface of the first fastening protrusion 171. The insertion groove 175 may be formed on both width-directional surfaces of the first fastening protrusion 171. A plate spring 141 of a fixing assembly 140 to be described below is inserted and locked in the insertion grooves 175, whereby it is possible to prevent the connecting bracket 150 from being separated from the fixing bracket (110, see FIG. 4) due to force that acts in the up-down direction. A detailed coupling method will be described with reference to FIGS. 7A to 7D.

FIG. 3 is a view showing the state in which the connecting bracket 150 according to an embodiment of the disclosure is coupled to communication equipment and FIG. 4 is a view briefly showing a method of coupling the connecting bracket 150 and the fixing bracket 110 of the device (100, see FIG. 1) for fixing communication equipment according to an embodiment of the disclosure.

Although the communication equipment 200 is bolted to a surface of the base (160, see FIG. 2) in FIG. 3, the disclosure is not limited thereto and various types such as fitting, latching, sliding may be used.
