An ostomy coupling has a pair of coupling rings. The body side ring has a flange attached to a medical grade adhesive pad and a chute wall surrounding a stomal aperture. The bag side ring has a rib member and a seal strip. To provide easy disengagement, the bag side ring has an integral flexible latching arm having a hook portion positioned to engage under a hook flange on the body side ring when the rings are coupled. The hook portion is disengagable from the hook flange by a lifting movement of the latching arm.
