Each valve portion (12, 14) comprises a housing (16, 18), a valve seat and a valve closure member (20, 20′). The assembly has a first configuration in which the first and second valve portions engage with one another, the valve closure members being closed, and a second configuration in which the two valve portions are disengaged from one another. The first valve portion has locking means (60) moveable relative to the second valve portion to selectively lock and unlock the two valve portions together.
