Abstract
A female pipe coupling member includes a coupling body and a sleevedisposed around a cylindrical peripheral wall portion of the coupling body. The sleeve has a locking element receiving hole extending therethrough from an inner peripheral surface to an outer peripheral surface. When the sleeve is in a locking element releasing position where the locking element receiving hole radially aligns with a locking element, the locking element is received in the locking element receiving hole to assume an unlocking position. The locking element receiving hole is configured to block the locking element from passing therethrough radially outward and thus holds the locking element in the unlocking position from outside.
