PROBLEM TO BE SOLVED: To provide a C-clip for a gas turbine engine. SOLUTION: The C-clip 56 includes an outer arcuate arm 60 having a first radius of curvature; an inner arcuate arm 58 having a second radius of curvature which is substantially greater than the first radius of curvature; and an arcuate flange 57 connecting the outer arcuate arm 60 and the inner arcuate arm 58. The flange 57, the outer arcuate arm 60, and the inner arcuate arm 58 collectively define a substantially C-shaped cross section. A shroud assembly 33 includes a shroud segment 32 with a mounting flange 54, and a shroud hanger with an arcuate hook 44 disposed in mating relationship to the mounting flange 54. The arcuate C-clip 56 having the inner and outer arcuate arms 56, 60, overlaps the hook 44 and the mounting flange 54. The shroud segment 32 and the C-clip 56 are subject to thermal expansion at a hot operating condition. One of the dimensions of the shroud segment 32 and the C-clip 58 is selected to produce a preselected dimensional relationship between them at the hot operating condition.
