an ostomy coupling has a first coupling ring 10 attachable to a medical grade adhesive pad ant a second coupling ring 20, engageable and disengageable with the first ring 10, attachable to an ostomy pouch. There is an intervening ring 30 loosely disposed between the first and second rings. The intervening ring has thereon a pair of tabs 31 substantially at opposite ends of a diameter. At least a part of each of these tabs is upwardly angled so that a wearer of the ostomy coupling can place a finger or thumb behind each of said tabs. According to another aspect an ostomy coupling comprises a first coupling ring attachable to a medical grade adhesive pad and a second coupling ring, connectable to the first ring and attachable to an ostomy pouch. The first ring has a flange portion and a wall of closed-loop shape extending substantially perpendicular to the flange and surrounding a stomal orifice. The wall has a radially outwardly-extending rim at its edge further from the flange. The first ring carries thereon a relatively rigid third ring having radially extending tabs at opposite ends of a diameter thereof. The third ring is slidable in an axial direction relative to the first ring. Interposed between the third ring and the said rim, is a fourth ring which is slidable to a limited extent in an axial direction of the first coupling ring. The function of the third and fourth rings 30, 40 is to assist in making a secure connection between the first and second rings while at the same time permitting a wearer to couple the first and second rings together, or to separate them, without applying a painful pressure to the peristomal area.
