PURPOSE: To provide a pipe connecting device to which a stopper can be easily mounted, and which is to be stably held after mounting, by providing a circular arc-like holding part wherein the part exceeding the specified angle from the mounting direction extends along the outer peripheral surface when the stopper is mounted on a cylindrical part of a socket part. CONSTITUTION: A stopper 10 is provided with a holding part 10a wherein the part exceeding 180 deg. from the mounting direction is formed into a circular arc shape along the outer peripheral surface of at least a cylindrical part 4A when the stopper 10 is extended in the axial direction of a pipe 11, and also when a stopper 10 is mounted on the cylindrical part 4A of a socket part 4. Since the holding part 10a of the stopper 10 is made into a state where it holds the cylindrical part 4A of the socket part 4 when a circular arc-like projecting line 7a of the stopper 10 is fitted into hole parts 5 of the receiving part 4 and then the stopper 10 is mounted on the socket part 4, the stopper 10 can be stably mounted on the outer peripheral surface of the socket part 4. When force is applied in the direction to open the stopper, the circular arc-shape part exceeding 180 deg. is hooked on the socket part 4, so as not to be easily opened, and it is hooked on the outer surface of the socket part 4. |
