<p><P>PROBLEM TO BE SOLVED: To provide a connection branch pipe capable of improving certainty of its construction and attaining laborsaving of piping work. <P>SOLUTION: In the connection branch pipe 1, a locking pawl 4 can pass through an opening 3 of a sewer 2 by rotating the pivoted pawl 4, rotation of the locking pawl 4 is prevented by screwing a connection member 9 into a locking member 6 to make the locking pawl 4 unable to pass through the opening 3 of the server 2. Upon keeping in contact with a pulling-out lock section arranged on a saddle member 7 and a contact section formed on the connection member 9, an opening of the saddle member 7 can be kept in a perfect circle, and a rotary operation of the connection member 9 can be smoothly performed in the connection branch pipe 1. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
