Manifold mounting arrangement

A manifold mounting arrangement comprising: a discrete manifold module; a clevis arrangement having a clevis straddling a flange and pivotally secured to the flange by a clevis pin; and a locking bar configured to be coupled to the clevis and to constrain the manifold module relative to the clevis arrangement in the locality of the locking bar. The invention finds utility for mounting case cooling manifolds to turbine casing for a gas turbine engine.
