Claims

[Claims for Utility Model Registration] (1) A core that can be inserted into and removed from the end of a pipe and has a body and a bottom plate, and a core that has a substantially cap-shaped cross section and is located on the front or back side of the bottom plate of the core, and an elastic metal piece whose peripheral edge expands in whole or in part to come into contact with the inner wall of the pipe when pressurized in the axial direction of the pipe, and the elastic metal piece is pressed against the bottom plate by a bolt or other screw. A structure for fixing a pipe end connector to a pipe, characterized by: (2) A core that can be inserted into and removed from an end of a pipe and has at least a pair of legs that are continuous with each other at one end, and each leg of the core and the corresponding leg when inserted into the end of the pipe. In the portion facing the inner wall of the pipe, one side is provided with a convex portion, and the other side is provided with a hole or a recessed portion for guiding the convex portion, and the convex portion is inserted into the hole or recessed portion, Structure of the fixed part of the pipe end connector to the pipe.
