ABSTRACT:
An apparatus for increasing the bending strength of tubes is provided. The apparatus may include an adapter and at least one sprint element. The adapter may have a shape that is matched to a cross-sectional shape of a tube end in such a manner that the adapter may be fitted to a tube connection of a device instead of the tube end and the tube end may be fitted to the adapter. The at least one spring element may be connected to the adapter. The at least one spring element may project out of the adapter in the direction of the tube. The at least one spring element may include a holding element at the projecting end. The holding element matches the cross-sectional shape of the tube and describes at least half the periphery of the tube. A fitted tube abuts against the holding element when the tube is subjected to bending. The rigidity of the spring element increases the bending strength of the tube in the region between the adapter unit and the holding element.
