A device for holding nested pipes to one another radially and axially thereof each at one end, comprising a substantially U-shaped hook member engageable with axially opposite side faces of an inner flange on one end of an outer pipe and also engageable at its bottom with an outer peripheral shoulder portion of one end of an inner pipe, an engaging member engageable with one end face of the inner pipe, and screw means for fastening these two members to each other. Like the hook member, the engaging member is preferably U-shaped. For holding at least three pipes together, an engaging member substantially resembling the hook member is used for the intermediate pipe. |
