解除できる。Further, when the outside of the lock member is covered with the cover in the pipe connected state as in the pipe connecting structure according to claim 2, even if an impact is applied from the outside,
The locking member is not deformed inward, and the pawl is not disengaged from the engaging hole. That is, it is possible to prevent the pipe connection from being accidentally released due to an external impact. Further, since the engagement release hole and the arm of the lock member have a coaxial positional relationship, the hook of the lock member and the engagement hole of the socket can be engaged simply by inserting the jig straight into the engagement release hole. Can be released.
