ABSTRACT:
A two-part ostomy bag assembly comprises a bag and a fitment secured around the stoma. The bag has a coupling in the form of a neck with an annular lip which is insertable in a deformable collar in the fitment. A resilient ring embraces the collar and has projecting tabs by which the ring can be tightened to deform the collar about the neck of the bag coupling. The lip prevents full tightening of the ring before the neck is fully inserted in the collar and the lip engages in an annular recess in the collar. The ring is retained in a tightened state by means of a releaseable ratchet arrangement.
