Abstract

The invention relates to a respiratory mask with an interface for the connection of at least two components, wherein the interface is round or oval and has a maximum diameter, and the components each make available at least one subregion of the interface. The component has a grip part which extends radially outward from the subregion and which is configured as a pressing surface or gripping means for fingers or the hand of an operator, wherein the component has two grip parts, wherein the subregions are in form-fit engagement with each other in an assembled state and are movable about a rotation axis (DA), for which purpose the grip part is rotatable to different rotation positions relative to the two grip parts.
