PROBLEM TO BE SOLVED: To reduce the size of a one-touch joint for low pressure and facilitate its operation by providing a plug with an arm spring which is continuous with an insertion port and a projection section, a socket with a sleeve section, a guide groove of the arm spring, a knotch hole which is engaged with the projection section, and a receive port, and an O ring between the receive port and the insertion port. SOLUTION: The connection work is done by matching an arm spring 16 with a guide groove 20 and inserting an insertion port 15 of a plug 13 into a receive port 22 of a socket 14. Since a projection section 17 slides inside the guide groove 20 and is engaged with a knotch hole 21 automatically at this time, it is unnecessary to operate the arm spring 16 for connection. Since fluid which passes a tube 12 and flows into the plug 13 and the socket 14 in the connection condition passes and flows at low pressure, it is possible to seal a section between an inner peripheral face of the socket 14 and an outer peripheral face of the plug 13 by an O ring 25. The disengaging work can be done by pressing a finger receive section 16a to oscillate the arm spring 16 and separating the socket 14 from the plug 13 in a condition in which the projection section 17 separates the knotch hole 21. Consequently, it is possible to facilitate the operation and simplify a structure of a one-touch joint. |
