PROBLEM TO BE SOLVED: To facilitate assembling of an optical fiber build-out in the job site and to hold a matching sleeve with high reliability by extending a mount flange to the outside of a longitudinal direction axis so as to leave from a tubular body. SOLUTION: A pair of first attaching flanges 21 which are spaced apart and faced each other are formed in a position of nearly a second end 15 of a cylindrical body 11 between first and second ends of the cylindrical body, and those flanges 21 are extended outward from the cylindrical body 11. Also, a pair of second attaching flanges 22 which are spaced apart and faced each other are provided as one part of the cylindrical body 11, and those attaching flanges 22 are respectively spaced apart from the respective first flanges 21 for receiving an attaching panel by snap fitting between those and also are faced each other. And an annular mount flange is formed in the middle part of the ends on an outer surface of the body, and the mount flange is extended from the axis in the outside direction and is formed into such a size and shape that it is housed in a build-out cap boy the form of snap fitting.
