Abstract
A flexible corrugated hose fitting, which is particularly provided for high-pressure installations, such as air conditioning installations using CO2 as the refrigerant, has a connecting element, which can be snapped together with the interior corrugated pipe of the flexible corrugated hose. In addition, the connecting element has sealing elements, which come into sealing contact with the corrugated pipe. Following the area receiving the sealing elements, the connecting element has a cone, which is used as a clamping section. An exterior squeeze ring, or other squeeze element, is used for pressing the exposed end of the corrugated pipe against the clamping section. A pressing sleeve is used for pressing, which drives the squeeze ring by a wedge effect inward. It has an appropriate conical interior surface. The squeeze ring moreover extends over the sheathing. For further securing of the connection, the pressing sleeve can be pressed together here with the sheathing by an appropriate deformation. The pressing sleeve can alternatively be provided with an interior thread in this area, which cuts into the sheathing.
