Abstract
A rectifier vane stage is connected to a stator that is supported at the internal end thereof by a connecting ring which includes a support ring and a stiffening ring, a retaining lip of which is inserted into the support ring and similarly into the recesses of the ends of the vanes. The possibility of the vane accidentally coming loose following breakage of said vane is therefore eliminated.
