<P>PROBLEM TO BE SOLVED: To provide a structure of a locking piece for preventing coming-off for a clip mounted in a connection part of connection pipes capable of integrally fixing on the clip before and after mounting and preventing increase of the number of mounting work processes. <P>SOLUTION: This structure of pipe connection is constituted by mutually joining the connection pipes provided with flange parts 101, 201, respectively, to form the connection part 300, mounting the clip 400 for preventing coming-off forming opening pieces 403, 404 at both ends in the connection part, and inserting a part of the flange parts in the connection part into window parts 405, 406 provided in the clip. This locking piece 10 is mounted on each opening piece of the clip, has a one-end opened square shape part 11 capable of covering a tip of the opening piece, forms a cut-out part 21 like a one-end opened square shape on a face 20 on one side constituting the one-end opened square part, forms a claw part 23 by inclining the inside of the cut-out part like one-end opened square shape onto an inner side by bending the face on one side outward, and forms leg pieces 31 abutting on a part around each connection pipe at both side positions of a face 30 on the other side constituting the one-end opened square shape part, respectively. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
