<p>PURPOSE: To prevent a mutual slip between a clip and flanges by providing a center rib part inserted between the flanges and extended downward so as to be frictionally engaged with an inside mating face when the clip is connected. CONSTITUTION: Tabs 2, 3 are formed along a spine 4 of a clip 1 with side ribs 9, 10 for clamp-locking flanges 11, 12 of ducts 13, 14. These tabs 2, 3 are bent upward from the spine 4 along folding lines 7, 8, bent downward at an acute angle and provided with ribs 5, 6 having tooth structure along a longitudinal centerline. The ribs 5, 6 driven between the flanges 11, 12 are frictionally engaged with these inner surfaces so as to prevent a slip along the flanges 11, 12 without using a special tool.</p> |
