Patent ID: 8651147

Claim:
An apparatus for increasing the bending strength of a tube, the apparatus comprising: an adapter unit having two regions, an internal diameter of a first region of the two regions being sized such that the first region is fittable to a tube connection of a device, and an external diameter of a second region of the two regions being sized such that the tube is fittable to the second region; and at least one spring element connected to the adapter unit and projecting out of the adapter unit in a direction of the tube and having a termination element at a projecting end, the termination element comprising a termination body, the termination body having a width greater than a width of the at least one spring element at the projecting end of the at least one spring element, the width of the termination body and the width of the at least one spring element being in a direction perpendicular to the direction of the projection, wherein the termination element abuts against the tube when the tube is subjected to bending, so that the rigidity of the at least one spring element increases the bending strength of the tube in a region between the adapter unit and the termination element.
