A diverging ring is displaceable between a retracted position in which it surrounds a first portion of a diverging part and a deployed position in which it is connected to a downstream end of the first portion. A deployment mechanism causes the diverging ring to move from its retracted position to its deployed position under drive from an actuator. A temporary structure, or &ldquo;insert&rdquo;, is placed inside the diverging ring so as to transform the diverging section thereof into a non-diverging section, at least over the major portion of the length of the diverging ring, the insert being eliminatable on or after the diverging ring coming into its deployed position.
