<P>PROBLEM TO BE SOLVED: To reliably prevent slipping out of a corrugated tube, simplify a connection work, and suppress projection farther in the external direction than the protrusion part of the corrugated tube, in a tube connection part formed with the end part of the corrugated tube having a protrusion part approximately into a square shape, in a cross section in the direction of a tube diameter direction is inserted into a engaging cylinder part approximately into a square shape for the cross section, in the direction of the tube diameter of the pipe joint. <P>SOLUTION: Locking pieces (22) and (22), formed of a thin metallic sheet, are situated on the inner wall surface of an engaging cylinder part (11). By forcibly spreading externally the locking pieces (22) and (22) against their elastic force by the protrusion part (2) of the corrugated tube (1), insertion of the corrugated tube (1) into the engaging cylinder part (11) is allowed; the locking pieces (22) and (22) are fitted in a gap between the adjoining protrusion parts (2) and (2) of the corrugated tube (1) inserted in the engaging cylinder part (11) by its elastic returning force; and by engaging it with the protrusion part (2), the slip out of the corrugated tube (1) from the engaging cylinder part (11) is prevented from occurring. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
