ABSTRACT:
A pipe coupler has male and female portions each adapted for attachment as by welding or the like to the ends of pipe lengths. The male element, which is non-circular in cross section, telescopes into a like configured bore in the female portion, with the forward end of the male coupler abutting an internal step of a female coupler. A pair of keys fit within parallel slots on opposite sides of the female coupler, and in position in aligned recesses provided in the male coupler. First and second edges of the key blocks are disposed at a small angle to each other, so that the keys may be wedged tightly into place holding the male and female couplers in fluid tight sealing relationship.
