The invention relates to a back or pelvic belt having adjacent pads (15, 16, 17, 18) that are attached to a support element (1) in the back area of the belt, with a respective clasp part (4a, 4b) being attached to each of the opposite edge areas (2, 3) of said support element (1) for applying the belt by joining the ends of the two clasp parts characterized in that two tension belts (9a, 9b) are provided on the support element (1) which are attached at the opposite edge areas (2, 3) of the support element (1) and are each guided across the pads (15, 16, 17, 18) in opposite directions such that the pads (15, 16, 17, 18) will approach each other when both tension belts (9a, 9b) are tightened, and will exert a pressure on the affected body part depending on the tensile force acting on the tension belts (9a, 9b).
