Zusammenfassung:	A plastic expansion type connecting and fixing device for pipes belongs to reinforcing parts of non-metallic materials and consists of an inner tube and an outer sleeve. The outer wall surface of the inner tube and the inner wall surface of the outer sleeve are both inclined in a bevel form, and the inner tube is pulled by means of tightening screws so that the outer sleeve is compressed to expand. The overall plastic expansion type connecting and fixing device for pipes is fixed in a pipe and can be connected with external bolts through embedded nuts. Without welding or glue adhesion, the plastic expansion type connecting and fixing device for pipes can be fixed in the pipe and can be connected with the external bolts through the embedded nuts.
