A female coupling member is provided for a pipe coupling that handles a high-pressure fluid. The female coupling member has collet-type locking members capable of correctly connecting the female coupling member and the associated male coupling member. The male coupling member receiving portion 22 has an inward inner surface 35 - 2 that slidingly engages a forward end outer peripheral surface 12 - 2 of the male coupling member 12 when the male coupling member 12 is inserted into the male coupling member receiving portion 22 and before as the male coupling member 12 reaches a position where the engaging portion 12 - 1 of the male coupling member 12 is engaged by the latch portions 32 - 1 of the locking members 32. The male coupling member receiving portion 22 further has a forward end inner surface 20 - 1 ( 2 ) that slidingly engages an outer peripheral surface 12 - 3 of the male coupling member 12 that is more rearward of the forward end outer peripheral surface 12 - 2 than the engaging portion 12 - 1 of the male coupling member 12 at the same time as the inward inner surface slidingly engages the forward end outer peripheral surface 12 - 2 of the male coupling member.
