PROBLEM TO BE SOLVED: To provide an optical fiber cable connection point temporary waterproof guard tool and its receptive hardwares preventing a hit failure and a disconnection failure due to bend/put-in to a coated optical fiber caused by an artificial and structural factor. SOLUTION: Two semicircular half division cylinder attaching metal fittings are connected detachably, and a circular half division cylinder attaching metal fitting 17 is formed, and the circular half division cylinder attaching metal fitting 17 is detained with internal metal goods 18 of both end standard closures of a coated fiber housing part 19, and a half division cylinder 16 formed by colorless, transparent hard row material is fitted to the outer peripheral surface of the circular half division cylinder attaching metal fitting 17 so as to nearly match with it attachably/detachably, and is made an integral cylindrical body enveloping a switch connection point. |
