Abstract
In joining an angle section with an elongated flexible body of an endoscopic insertion instrument, a connector ring on the side of the angle section and a connector ring on the side of the flexible body are connected by fitting engagement, one connector ring on the outer side of the other connector ring. A number of inwardly projecting ridges are provided on the inner periphery of the inner connector ring, and screw holes are bored radially through the inwardly projecting ridges. On the other hand, a number of perforations are provided in the outer connector ring at positions corresponding to the screw holes in the inner connector ring. Screw members are threaded into the respective screw holes of the inner connector ring through the perforations in the outer connector ring. Further, a screw anchor ring is slidably fitted on the outer connector ring. The screw anchor ring can be shifted to and from a covering position to close on head portions of the screw members and an uncovering position to uncover and expose head portions of the screw members.
