ABSTRACT:
A joint for piping includes a pipe with an annular swelling wall and a connector body with a socket that includes locking pieces. The locking pieces hold the annular swelling wall when the pipe is inserted through the connector body to connector the pipe to the connector body. A projected member on the pipe fits in a recess on the connector body to prevent rotation between the pipe and the connector body.
