ABSTRACT:
A tube connection is provided for thin-walled, small calibre metal tubes 15,22, particularly for brake, fuel and hydraulic lines on motor vehicles and for use in refrigeration equipment, with at least one of the metal tubes 15,22 being provided with a flange 14,21 on the end to be connected and the metal tubes 15,22 being encompassed by a sleeve 1,2 in each case, one of which is deformable so as to form a fixed connection between the sleeves 1,2, the deformable sleeve 1 being constructed as an outer sleeve which encircles the other sleeve 2 constructed as an inner sleeve in the assembled condition at least over a portion of its length. The inner sleeve 2 is provided with a circular thicker portion 23 at the end nearest the flange 21 so that a part of the outer sleeve 1 is deformable behind this thicker portion 23 (FIG. 3).
