<p>PURPOSE:To disuse an operation space by forming circular grooves on an outer circumference of a male joint, slidably fitting a sleeve having a connection member and an escape preventing member thereto, and pressing the sleeve in one direction by means of a spring. CONSTITUTION:Circular grooves 6, 7 are formed on an outer circumference of a male joint 2, while a sleeve 11 having a disappearable connection member 8 and an escape preventing means 9 is slidably engaged with the outer circumference of the male joint 2. The sleeve 11 is pressed in one direction by means of a spring 10 to fit a sealing member 12 to the circular groove 7. The operating space for the sleeve 11 is dispensed with, accordingly, since the sleeve 11 is operated only by pressing the male joint 2 into a female joint 4, without manual operation of the sleeve 11.</p> |
