Abstract

A device for connecting support rails (1, 1', 1") for heat exchanger tubes (2) is described, comprising a first connecting section (6) which can be inserted in a rotationally fixed manner into a tube receptacle (4) of a first support rail (1), has a connecting section longitudinal axis (5), is assigned to said first connecting section an anti-twist device acting about said connecting section longitudinal axis (5), and comprises a second connecting section (6') which is designed such that it can be connected to a second support rail (1') whose supporting rail longitudinal axis (7') runs parallel to the connecting section longitudinal axis (5) of the first connecting section (6). This prevents the heat exchanger tubes (2) from buckling in the apex region of pipe bends.
