Abstract
The invention relates to an extension (30) of an intermediate casing for an aircraft jet engine, intended to project towards the downstream end from an external shell of the intermediate casing, this extension comprising an annular connecting downstream end (64) forming an annular groove (66) open radially towards the outside, intended to receive nacelle covers. According to the invention, the annular connecting downstream end (64) is produced by means of a plurality of angular sectors (76a, 76b).
