SOLUTION: A connector 10 for quickly connecting a pipe with a groove end part is provided with stop rings 16 and 18 each normally having a diameter larger than the pipe to be connected, the stop rings 16 and 18 are contracted and fixed during fastening and at this time, the inner diameters of the stop rings 16 and 18 are smaller than the diameter of the pipe. The outer diameter of the stop rings 16 and 18 are larger than the annular groove of a connector main body 12 and by the fastening of the stop rings 16 and 18, the disconnection of the pipe from the connector 10 is prevented.</p> |
