Claim:
A method of covering a wire harness branch section with a protector, the branch section being a T-shaped section where a branch wire branches from a main wire of the wire harness, the protector being provided with a T-shaped cylindrical body including a lateral cylindrical section covering the main wire and a longitudinal cylindrical section covering the branch wire, the protector comprising: a main body and a cover, which are a pair of T-shaped semi-annular sections formed by splitting the T-shaped cylindrical body into two; and thin hinges connecting the main body and the cover at external split ends of the lateral cylinder semi-annular sections; wherein the cover is placed over the main body pivoting the thin hinges, so that first opening and closing ends provided opposite to each other on the lateral cylinder semi-annular sections of the main body and the cover are locked and connected, and that second opening and closing ends provided opposite to each other on the longitudinal cylinder semi-annular sections are locked and connected; the method comprising: hooking and placing the cover of the protector in an open state on an upper end portion of a pressing wall of a setting jig, which is provided with a main body receiving recess as an upper surface opening having a cross-sectionally arcuate shape and with the pressing wall projecting upward from one side end of the main body receiving recess; positioning and setting the main body above the main body receiving recess; inserting the main wire and the branch wire of the wire harness into the main body of the protector; setting the wires into the main body receiving recess; and thereby the pressing wall presses the cover; the cover rotates toward the main body; and locking portions provided on the main body engage with locked portions provided on the cover, thus locking the first opening and closing ends of the lateral cylindrical section and the second opening and closing ends of the longitudinal cylindrical section.
