1. A header for a heat exchanger adapted to have a refrigerant fluid passed through it and comprising:
a wall delimiting a chamber accommodating a distribution device for distribution of the refrigerant fluid inside the chamber, wherein the chamber and the distribution device are coaxial along a longitudinal axis centered on a transversely median axis of the header that extends in a longitudinal direction of the header,
the distribution device comprising at least one conduit extending between two ends along the longitudinal axis, at least a first end of the conduit being provided with an inlet opening for the admission of the refrigerant fluid to the interior of the distribution device,
the distribution device being provided with at least one orifice oriented transversely to the longitudinal axis for the evacuation of the refrigerant fluid from the distribution device to the chamber; and
at least one member for retaining the distribution device inside the chamber at least in part made in one piece with the wall of the header,
wherein the retaining member comprises at least one finger made in one piece with the wall of the header and an opening delimited by the conduit, the at least one finger being accommodated in the opening and centered on the longitudinal axis to form a plug in the opening,
wherein the wall of the header comprises at least one cover, wherein a cross-section of the at least one cover has a profile in a shape of a semi-circle extending a full length of the at least one cover, and
wherein the at least one cover extends along the longitudinal axis, wherein at least one flange is disposed at a longitudinal end of the cover and the at least one flange is oriented transversely to the longitudinal axis, and wherein the at least one cover comprises an opening to receive a notch of the at least one flange.
