A first coupling of a first protector includes a U-shaped inner wall section and a cover. The inner wall section has an inner bottom wall and opposed inner side walls. The cover extends from outer surfaces of the inner bottom wall and opposed inner side walls of the inner wall section to a distal end opening in the first coupling. The cover is open at a distal end. A second coupling of a second protector includes a bottom wall and opposed side walls that are inserted through the distal end opening into a clearance defined between the inner wall section and the cover of the first protector. The first and second couplings of the first and second protectors are connected together so that the second coupling of the second protector is caught between the inner wall and the cover of the first coupling of the first protector.

1. A protector for a wire harness comprising: a first protector member made of a resin molding product and having a U-shaped configuration in cross section that includes a bottom wall and parallel opposed side walls, said first protector member being provided on a longitudinal end with a first coupling portion; anda second protector member made of a resin molding product and having a U-shaped configuration in cross section that includes a bottom wall and parallel opposed side walls, said second protector member being provided on a longitudinal end with a second coupling portion;said first and second coupling portions being connected to each other;said first coupling portion of said first protector member including an inner wall section having a U-shaped cross section and a cover section, said inner wall section having an inner bottom wall and parallel opposed inner side walls that are continuously connected to said parallel opposed side walls of said first protector member, and said cover section extending from an outer surface of said inner bottom wall through opposite corners to said opposed inner side walls of said inner wall section to define a double wall structure, said cover section projecting to a distal end opening in said first protector member, said double wall structure being open at a coupling end, said inner bottom wall or said opposed inner side walls of said inner wall section being provided with a through-hole, and a clearance being defined between said inner wall section and said cover section;said second coupling portion of said second protector member including a bottom wall and opposed side walls that are inserted through said distal end opening into said clearance in said first coupling portion, said opposed side walls of said second coupling portion being continuously connected to said opposed side walls of said second protector member, said bottom wall of said second coupling portion being disposed at a lower position than said bottom wall of said second protector member, and said second coupling portion being provided on said bottom wall of said second coupling portion or opposed side walls of said second coupling portion with a protrusion to be fitted in said through-hole in said inner wall section;said first and second coupling portions of said first and second protector members being adapted to define a triple wall structure in which said second coupling portion of said second protector member is caught between said inner wall section of said first coupling portion and said cover section of said first coupling portion having said double wall structure, and said bottom walls of said first and second protector members being continuously connected to each other without causing a stepped portion. 2. A protector for a wire harness according to claim 1, wherein said first and second protector members include first and second lids, respectively, and each of said lids is provided on an end at laterally opposite sides with a locking portion extending downward from an upper wall of each of said lids; wherein one of said first and second coupling portions of said first and second protector members is provided on upper outer surfaces of said opposed side walls thereof with two portions being locked; andwherein said locking portions on said first and second lids of said first and second protector members engage with said portions being locked when said first and second coupling portions of said first and second protector members are connected to each other. 3. A protector for a wire harness according to claim 1, wherein said cover section provided on said first coupling portion of said first protector member is formed into a U-shaped configuration in cross section that covers a whole surface of said inner bottom wall of said first coupling portion and lower parts of said opposed inner side walls of said inner wall section of said first coupling portion, or a pair of L-shaped configurations in cross section that cover opposite corner portions between said inner bottom wall of said first coupling portion and said opposed inner side walls of said inner wall section of said first coupling portion; wherein an inner end of said cover section at a side opposite to said distal end opening projects from said inner bottom wall of said first coupling portion and said opposed inner side walls of said inner wall section of said first coupling portion, and said projecting inner end is bent in parallel to said inner bottom wall of said first coupling portion and said opposed inner side walls of said inner wall section of said first coupling portion to define said clearance and is extended to said distal end opening; andwherein said first coupling portion of said first protector member is provided in said inner bottom wall thereof with said through-hole and said second coupling portion of said second protector member is provided on said bottom wall thereof with said protrusion. 4. A protector for a wire harness according to claim 1, wherein said first and second protector members are coupled through said first and second coupling portions to each other in a bent connection manner.
