1. A profiled part for a heat exchanger, configured to have at least one fluid flow tube passing therethrough, comprising, for each flow tube, a hollow cylinder comprising an inner surface configured to receive said flow tube, the cylinder having, in the absence of any mechanical force, a circular cross-section with an inner diameter which is substantially constant over its whole length and substantially equal to the outer diameter of said flow tube, wherein the profiled part comprises a slit extending over the whole length of the cylinder and configured to permit, by application of at least one mechanical force to the profiled part, an increase or decrease in the inner diameter of the cylinder in order respectively to permit the insertion of the tube into the cylinder or the clamping of the tube by the inner surface of the cylinder.
