PURPOSE: A pipe connection unit is provided to stably fix and maintain the water tightness between a pipe and a connection body as the outer circumference of the pipe and the inner circumference of the connection body are strongly pressed by a packing and a fixing ring with simple operation. CONSTITUTION: A pipe connection unit includes a packing (40), and fixing rings (25,26). The packing is inserted into the outer circumference of a pipe (P) which is the object of connection by being formed in a cylindrical shape. The fixing ring is the cylindrical shape, and one side is slantingly separated. The upper end of the fixing ring faces the inner circumference surface (33) of a connection container. The lower end of the fixing ring faces the outer circumference of the pipe. The fixing rings are inserted into each other so that the fixing rings are interlocked. Both sides of the fixing ring are slantingly formed in a diagonal shape. One side of the fixing ring is formed in the diagonal shape so that the fixing rings are inserted into each other in order to be interlocked. |
