Abstract
A pipe coupling comprises a socket including a valve body, socket body having holes, lock balls stored in the holes for pressing the lock balls radially inward at an advanced position and for releasing the lock balls at a retracted position, and a plug having an engaging groove and being adapted to open the fluid passage when the plug is engaged with the socket. The holes in the socket include first and second holes individually extending in the axial direction, the first holes extending closer to the distal end side than the second holes. The valve body is returned to a position in which the fluid passage is closed, when the lock balls are located on the extreme distal end side of the first holes.
