A mounting hook for a tube (2) in the exhaust system of a motor vehicle, includes a pin (3) with an essentially cylindrical fixing end (7), at least one spacer and at least one spacer (8) with a mounting piece (12), for the fixing end, at a first end thereof and at least one fixing plate (11) for a tube (2), at the second end thereof. The at least one mounting piece (12) and the fixing end (7) are joined by welding. The at least one mounting piece and the fixing end cooperate via a planar contact matching the angle such as to permit an adjustment of the distance between the pin and the at least one fixing plate for a tube before welding.
