ABSTRACT:
A female coupling member of a pipe coupling is provided with a cap-like retainer removably mounted thereon and having an inner tapered surface. A male coupling member includes a cylindrical portion inserted into an axial bore in the female coupling member and a split elastic cotter ring retained on the cylindrical portion. When the male coupling member is pulled back, the cotter ring is brought into engagement with the tapered surface of the cap-like retainer to couple the coupling members to each other.
