A cap () for a header box of a heat exchanger (), in particular for a motor vehicle, in particular a radiator, is disclosed. This cap includes a head (), a shank () comprising at least one mounting thread (), this shank being between the head and a free end of the cap, a retaining lug (), in particular elastically deformable, arranged to retain the cap in an opening () of the header box in an intermediate position of the cap, in which position the cap leaves a clear passage while being retained in the opening, this retaining lug being formed on the shank.

Cap for a header box

The invention relates to a heat exchanger tube produced by bending a metal strip (), characterized in that said strip () has a thickness that can vary between at least one first thickness (e) and at least one second thickness (e) greater than said first thickness (e), and in that said tube has thinned first zones (Z1) and reinforced second zones (Z2) located at the points of greatest mechanical stress, said first zones (Z1) being formed by first portions (P1) of said strip of first thickness (e) and said reinforced second zones (Z2) being formed by second portions (P2) of said strip () of second thickness (e). The invention also relates to a heat exchanger comprising a core bundle of such tubes, and to a method of obtaining such a tube.
