A segmented seal (36) is provided for sealing between two adjacent rotor disks (18, 20). The individual segments (36) includes sideplate members (42, 44) and integral hook members (50, 52) which engage the facing sides of the respective disks (18, 20). Strut members (60, 62) support the central port
