Claims

[Scope of Claim for Utility Model Registration] 1. An intermediate joint pipe having sockets at both ends with an engaging flange formed on the outer circumferential surface and a packing locking groove on the inner circumferential surface, and an engaging flange formed on the outer circumferential surface. A pair of end joint pipes, each having a socket portion having a packing locking groove on its inner circumferential surface at the end thereof, the socket portion facing the socket portion of the intermediate joint pipe and coaxially disposed therein. and a connecting pipe which is inserted concentrically across the inner sides of the opposing sockets of the intermediate joint pipe and the end joint pipe, and has an annular protrusion on the outer periphery of the center, and the intermediate joint pipe and the end part. A packing that is held in a packing locking groove on the inner periphery of each socket of the joint pipe and is inserted in the gap with the connecting pipe and has a self-sealing action, and a packing that is made of a plurality of split bodies and is tightened in the radial direction by a fastener. annular engagement flanges protrude from the inner periphery of both ends, a central protrusion having an engagement groove for receiving the annular protrusion of the connecting pipe is provided on the inner periphery of the center, and the intermediate joint pipe and the end An expandable flexible joint tube comprising: an annular housing that is loosely fitted onto the engaging flanges so as to straddle the outsides of opposing socket portions of the joint tube. 2. The telescopic flexible joint tube according to claim 1, in which a wiper is attached to the engaging flange of the housing. 3. The telescopic flexible joint tube according to either claim 1 or 2 of the utility model registration claim, in which the housing is divided into two. 4. The telescopic flexible joint pipe according to any one of claims 1 to 3 of the claims registered as a utility model, in which the intermediate joint pipe has a straight pipe shape.
