1. An ostomy appliance comprising:
inner and outer walls of flexible sheet material joined together to define a cavity for containing a stomal output, the inner wall comprising an inlet for receiving the stomal output into the cavity;
a retractable drain being slidably movable between an extended configuration for draining the stomal output from the cavity and a retracted configuration for storage of the retractable drain; and
a push element for pushing the retractable drain into the retracted configuration, the push element comprising a strip of material having higher rigidity than the flexible sheet material of the inner wall and/or the outer wall;
wherein the retractable drain comprises a closure portion which may be turned up to close an outlet opening of the retractable drain and a first fastener configured to fasten the closure portion in place once turned up;
wherein at least a portion of the closure portion and the first fastener are positioned in a channel when the retractable drain is in the retracted configuration;
wherein the first fastener is configured to be operable independently of the push element, and wherein the push element and the first fastener are formed as separate components.
