A coupling sealing device of a union of a meter is provided to easily attach the sealing device to the union through a one-touch method, detect whether a user loosens the union and easily separate the sealing device from the union. A coupling sealing device(100) includes a pair of bodies(110,120). The bodies accommodate a union and are constructed in a manner that a smaller body is inserted into a larger body. A minor joint(123) having a wedge(124) is formed at one end of the smaller body. A major joint(113) having a mounting hole(114) is formed at one end of the larger body. A guide(129) is projected from the other end of the smaller body. A guide groove(119) corresponding to the guide is formed inside the larger body. |
