Abstract
A pipe connector comprises a plug having a groove on the outer periphery of the distal end portion thereof, a socket having an axial hole to receive the distal end portion of the plug and a radial hole, a sealing member attached to the socket and sealing the plug and the socket, a lever pivotally mounted on the socket adjacent the radial hole and having a cam engagable with the groove through the radial hole, the lever being movable to a connected position, a half-connected position and a separated position. The cam is engaged with the groove and the sealing member is pressed, while the lever remains in the connected position, the cam is partly engaged with the groove and the sealing member is free from pressure, while the lever remains in the half-connected position, and the cam is disengaged from the groove, allowing the plug and the socket to move relative to each other, while the lever remains in the separated position. The pipe connector further comprises a locking mechanism for preventing the lever from moving with respect to the socket when the lever is in the connected and half-connected position.
