Lie Groups and Lie Algebras, chapter IX, § 2. Maximal tori of compact Lie groups
With the notations of Prop. 4, every closed subgroup of G containing H and such that is finite normalizes H, and hence is contained in N; similarly, the normalizer of is contained in N. In particular, N is its own normalizer.
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.
