Topologie algébrique, chapter IV, § 6. Espaces classifiants
An alternative proof of these results would consist in verifying that the isomorphisms of fibre spaces constructed in prop. 2 and its corollaries are isomorphisms of principal fibre spaces.
Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
