Further, the first locking surface 32 is disposed opposite to the mating inclined surface 31 to define a first locking passage 33. In this way, after the first locking portion 44 enters the first locking passage 33, the fitting 30 can be locked and restrained. Specifically, the first locking surface 32 is disposed opposite to the mating inclined surface 31 in the second direction to define a first locking channel 33.
