The connection device () according to the invention has a locking head () that can be locked to an opening () of a container wall (). A clamping device () is also provided on the corresponding coupling piece (), which serves to tighten the head () locked to the container wall () without a rotational movement against the container wall (). The clamping device () can be designed as a wedge-clamping device (). The latter permits generation of large clamping forces with small operating forces. The clamping device () is preferably secured by a locking device (), so that vibration-proof connection resistant to temperature changes is achieved during simple assembly.

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.

A coupling assembly for connecting two tubular elements, in particular ends of two tubes of an air-conditioning system, includes two inter-engaging locking parts which, for the purpose of achieving a locked position, can be rotated with respect to one another and can be displaced with respect to one another in the axial direction. The locking parts utilize a bayonet locking feature and include at least two sub-elements, the sub-elements being fixed in the radial direction by two inter-engaging sleeves.
