Abstract
A pipe connecting device includes a female connecting member and a male connecting member. The female and the male connecting member can be restrained from turning relative to each other without using additional locking cover or the like and without being subject to various restrictions placed by actual piping conditions. A retainer (46) is provided with retaining parts (56a, 56b) that engage with an annular ridge (54) formed on the male connecting member (44) to restrain the male connecting member (44) from axial movement relative to the female connecting member (42), A noncircular part of the male connecting member (44) and the retaining parts (56a and 56b) of the retainer (46) constitute a locking structure for restraining the male and the female connecting member (44, 42) from turning relative to each other.
