An annular vane assembly for a gas turbine engine is provided. The assembly includes a vane segment, the vane segment includes an arcuate rail and a vane that extends radially inwardly from the arcuate rail. The assembly also includes a hollow cylindrical casing, the inside curved surface of which an annular groove is formed that receives the arcuate rail. The arcuate rail is secured in the annular groove using a resilient strip interposed between the rail and the groove. The resilient strip includes a planar main body and sprung wings that extend to either side of the main body. The wings are angled with respect to the plane of the main body. The resilient strip is moveable circumferentially between a first position in which the strip exerts a force radially on the arcuate rail and a second position in which the wings occupy recesses in the assembly.
