Abstract
A pipe coupler includes a tubular member internally defining a tubular passage communicable with a front opening and a rear pipe connector thereof; a valve head movably set in the tubular passage for openably sealing the front opening; a retaining ring fitted in the tubular passage adjacent to the rear pipe connector and including a hollow cylindrical section; and a return spring set in the tubular passage between the valve head and the retaining ring. The cylindrical section of the retaining ring has two circumferentially opposite free ends defining an elastically compressible gap between them, and an outer contact surface corresponding to an inner side of the tubular member. The tubular member is internally provided near the rear pipe connector with an annular groove, and the contact surface is provided with a round flange engaged with the annular groove to hold the retaining ring in place in the tubular member.
