<p>PROBLEM TO BE SOLVED: To provide duct connecting joints which simplify the work of connecting ducts for an air passage even in a narrow space. SOLUTION: First, joining parts 3 in a state wherein the cylindrical ducts (not shown in Fig.) for the air passage connected to connecting parts 2 respectively are made to face each other and then made to mate with each other by sliding the joining parts 3 mutually. In other words, the two duct connecting joints 1 are moved till the end parts of two sides of one duct connecting joint 1 where no slip-off preventing parts 4 are formed come into contact with regulating pieces 41 of the other duct connecting joint 1 respectively. When the two duct connecting joints 1 are thereby made to mate with each other, they are joined by two slip-off preventing pieces 42 of each joint 1, by four pieces in total, so that they may not disconnect from each other, and consequently the ducts for the air passage are connected with each other.</p> |
