a second coupling part configured for releasably attaching to the appliance coupling part; and

a flexible collar between the first and second coupling parts, the flexible collar permitting the second coupling part to be displaced away from the first coupling part, to provide a space for a user manually to brace the second coupling part when fitting the ostomy appliance wherein the body fitment with adapter attached has a profile height not significantly greater than that of the body fitment alone.

2. The adapter according to claim 1 , wherein the adapter has a through passage, and the first and second coupling parts and the flexible collar each extend around the through passage.

3. The adapter according to claim 1 , wherein at least one of the first and second coupling parts comprises a mechanical interlock profile.

4. The adapter according to claim 3 , wherein the mechanical interlock profile is selected from: a channel; and a rib.

5. The adapter according to claim 4 , wherein the one of first and second coupling parts comprises a channel and the other comprises a rib.

6. The adapter according to claim 1 , wherein at least one of the first and second coupling parts comprises an adhesive coupling part.

7. The adapter according to claim 1 , wherein at least one of the first and second coupling parts comprises a generally planar non-adhesive landing surface for engaging a complementary adhesive coupling part.

8. The adapter according to claim 1 , wherein the flexible collar comprises stretchable material.

9. The adapter according to claim 1 , wherein the flexible collar comprises foamed material.

10. The adapter according to claim 1 , wherein the flexible collar comprises substantially flat material.

11. The adapter according to claim 1 , wherein the flexible collar comprises flexible film material.

12. The adapter according to claim 1 , wherein the flexible collar is formed with accordion folds.

13. The adapter according to claim 1 , wherein the first and second coupling parts have different orifice dimensions.

14. The adapter according to claim 1 , wherein the internal dimension of the second coupling part is not smaller than the external dimension of the first coupling part.

15. The adapter according to claim 1 , wherein the first and second coupling parts are of substantially the same coupling size.

16. The adapter according to claim 1 , wherein the first and second coupling parts and the flexible collar are formed as one unit.

17. The adapter according to claim 1 , wherein the first and second coupling parts are formed as one unit and the flexible collar is a separate unit.

18. The adapter according to claim 1 , wherein the first coupling part and the flexible collar are formed as one unit and the second coupling part is a separate unit.

19. The adapter according to claim 1 , wherein the second coupling part and the flexible collar are formed as one unit and the first coupling part is a separate unit.

20. An ostomy apparatus comprising:

a body fitment comprising an adhesive wafer for attachment to the skin, and

a body fitment coupling part, the body fitment coupling part including a stomal orifice; and

an adapter for coupling to the body fitment, the adapter including a first coupling part for attaching to the body fitment coupling part, a second coupling part for releasably attaching to an ostomy appliance, and a flexible collar between the first and second coupling parts, the adapter having a through passage around which the first and second coupling parts and the flexible collar each extend, and the flexible collar permitting, in use, an ostomate to displace the second coupling part to create a space between the second coupling part and the body fitment to manually brace the second coupling part against an attachment force when attaching the appliance to the second coupling part wherein the body fitment with adapter attached has a profile height not significantly greater than that of the body fitment alone.

21. The apparatus according to claim 20 , wherein at least a portion of the body fitment coupling part is substantially fixed in position with respect to the adhesive wafer.

22. The apparatus according to claim 20 , further comprising an ostomy appliance having an appliance coupling part extending around an entrance aperture, wherein the second coupling part is configured for releasable attachment to the appliance coupling part.

23. A method comprising:

providing a body fitment having a non-floatable body fitment coupling part;

providing an adapter comprising a first coupling part, a second coupling part, and a flexible collar between the first and second coupling parts; and

attaching the first coupling part of the adapter to the non-floatable body fitment coupling part, in order to provide a floatable coupling part characteristic for the body fitment wherein the body fitment with adapter attached has a profile height not significantly greater than that of the body fitment alone.

24. Use of an adapter to provide a floatable coupling characteristic for a body fitment that has a non-floatable body fitment coupling part, the adapter comprising:

a first coupling part for attaching to the non-floatable body fitment coupling part;

a second coupling part for releasably attaching to an ostomy appliance; and

a flexible collar between the first and second coupling parts, the flexible collar permitting displacement of the second coupling part with respect to the first coupling part wherein the body fitment with adapter attached has a profile height not significantly greater than that of the body fitment alone.
