The spanner head has an opening portion which is larger than an outer diameter of a pipe to be connected, and is smaller than an outer diameter of a connection nut to be tightened. Moreover, the spanner head into which the pipe is inserted is moved along the pipe, the connection nut is inserted into a lower portion of the spanner to tighten the connection nut. |
