PIPE BODY AND PIPE CONNECTING DEVICE

Japanese Patent JP2017002934

A

PROBLEM TO BE SOLVED: To provide a pipe body in which a proper cut position of the pipe body is guided, and the insufficient insertion of a connection end part to an insertion port can be easily recognized.SOLUTION: A connection end part A1 of a pipe body A is cut along a cut mark 1 of an outer surface A2 between a first mark 2 and a second mark 3. If a cut position is appropriate, an interval between a cut face A3 of the pipe body A and the succeeding first mark 2 becomes shorter than an insertion dimension L, and an interval between the cut face A3 of the pipe body A and the succeeding second mark 3 becomes longer than the insertion dimension L. Therefore, by appropriately inserting the connection end part A1 which is appropriately cut into an insertion port 11 of an insertion object B by the insertion dimension L, the succeeding first mark 2 is concealed by being embedded into the insertion port 11, and the succeeding second mark 3 is exposed from the insertion port 11. If the insertion of the connection end part A1 into the insertion port 11 is insufficient, both the succeeding first mark 2 and the succeeding second mark 3 are exposed from the insertion port 11.SELECTED DRAWING: Figure 1
