ABSTRACT:
A pipe connector comprises sockets each having a rear cylindrical member connected to an associated one of first pipes, plugs each having a plug body connected to an associated one of the second pipes, and a locking mechanism, provided on each socket, for locking the associated plug. The pipe connector further comprises an inner cylindrical member having a plurality of housing sections for housing the rear cylindrical members, and a coupling portion for coupling the housing sections, and a main cylindrical member, extending in the axial direction of the housing sections, for movably containing the housing sections. The coupling portion and the main cylindrical member have a pair of holes formed to correspond to each other, one of the pair of holes having a tapered surface inclined with respect to the axial direction. The other of the pair of the holes contains a cam member. When the plug body is locked to the associated socket by the locking mechanism, the cam member is externally driven to cooperate with the tapered surface, thereby moving the main cylindrical member and the inner cylindrical member relative to each other in the axial direction of the housing sections and bringing the plug body and rear cylindrical member into contact with each other in the axial direction thereof.
