Annular, circumferentially segmented components of a gas turbine engine are secured to a support structure by C-shaped couplings which prevent movement of the components in a radial and circumferential direction. The coupling has spaced apart legs which trap the component and support structure therebetween, and a key between the legs which engages a keyway formed by cooperating slots in the component and support structure.

A gas turbine engine assembly, comprising: (a) an annular engine case having an annular, axially extending rail thereon, said rail having a plurality of axially extending, circumferentially spaced apart slots therein; (b) an annular engine component comprising a plurality of arcuate, circumferentially disposed segments, each segment having an axially extending flange in overlapping contact with said rail, each flange having an axially extending slot therein radially aligned with one of said rail slots to form a keyway; and (c) a plurality of couplings, each coupling having two spaced apart legs, both legs extending axially from and integral with a back, said legs and back forming a C-shaped structure, wherein said overlapping portions of said rail and at least one of said segment flanges are disposed between and are contacted by said legs of one of said couplings, and said legs of said one coupling prevent relative radial movement between said rail and at least one of said flanges, and wherein each coupling has an axially extending key disposed between said legs and integral with at least one of said legs or with said back, wherein said key of one of said couplings engages one of said keyways and prevents relative circumferential movement between said rail and at least one of said flanges.
