A tracheostomy airway device is provided comprising an outer cannula (110) having open proximal and distal ends, an inner actuation member insertable into the proximal end of the outer cannula, and one or more retention members (130). The one or more retention members are movable relative to the outer cannula between a retracted configuration in which the tracheostomy device is insertable into, and removable from, the trachea of a patient, and an extended configuration in which the one or more retention members impede removal of the tracheostomy airway device from the trachea. The retention members are operably linked to the inner actuation member or the outer cannula, such that movement of the inner actuation member relative to the outer cannula actuates movement of the one or more retention members between the retracted configuration and the extended configuration.
