The matrix or die and sliding block, along with a bearing shoulder for the tube to be bent, are retractable in a direction at right angles to the bending plane. In addition to the bending assembly, the apparatus comprises clamping devices and also structure for automatic centering of the tube and taking up of the tolerance on the legs or between different bendings. These last mentioned devices are arranged in line in a same structure, the bending and clamping devices being mounted on slides.
