1. An applicator for a nasal cannula, comprising: a body enclosing a hollow space; a first tube connection and a second tube connection for supplying a respirable gas into the hollow space, the first tube connection and the second tube connection being integrally formed on the body; a first prong and a second prong for administering the respirable gas into the nostrils of a user, the first prong and the second prong being integrally formed on the body; a valve in a wall of the body, the valve being constructed such that the respirable gas, independent of the respirable gas supplied via the first tube connection and the second tube connection, can flow directly from an outside of the body through the valve into the hollow space and then further to the first prong and the second prong, wherein the valve inhibits gas flow from the hollow space through the valve to the outside of the body; and a top that is slipped over the first prong and the second prong for sealing between the first prong and the second prong and an inner wall of a respective nostril, said top being formed of a first sealing cone and a second sealing cone, wherein the first sealing cone and the second sealing cone have on a side facing away from the body a different cross-section area and a different cross-section shape than on a side facing the body, said first sealing cone and said second sealing cone being mechanically connected by a bridge on the side facing the body.
