The holonomy correction is one of the main terms arising when implementing loop quantum gravity ideas at an effective level in cosmology. The recent construction of an anomaly-free algebra has shown that the formalism used, up to now, to derive the primordial spectrum of fluctuations was not correct. This paper aims at computing the tensor spectrum in a fully consistent way within this deformed and closed algebra.
