ABSTRACT:
The piping connector according to the present invention is comprised of a conducting pipe having an annular expanded wall in the proximity of an end part of the pipe, a main body of a joint provided with a structure formed at one end thereof for accepting the conducting pipe thereinto and provided with a circulating hole formed in the axial direction on the other end part thereof in communication with the conducting pipe mentioned above, a sealing means to be fit into the inside area of the main body of the joint, and a retaining means installed inside the main body of the joint, wherein the retaining means mentioned above is comprised of an arm part formed of an elastic body in a shape resembling that of the letter C, and a socket unit comprised of a plurality of suspending parts projecting from the arm part in the direction of the inside diameter and inserted into notched windows formed in the main body of the joint and disposed so as to be put into their direct contact with the annular expanded wall of the conducting pipe, so that the socket unit opens and closes in the radial direction in reaction to the insertion of the conducting pipe and holds the conducting pipe in its proper position in collaboration with the main body of the joint. Further, the construction of the piping connector may be effectively modified within the technical scope of the present invention as described in the present Specification.
