An anti-rotation bracket for restraining rotational and axial movement of an oil supply tube in an aircraft gas turbine engine during assembly and disassembly of a flanged connection between segments of the tube. The bracket includes a leg which extends about an adjacent stiffening ring of the turbine frame, a body portion having a substantially U-shaped channel opening to the leg for positioning the bracket around the oil supply tube, and a plurality of elongated holes passing through the body portion for clamping the bracket to the oil supply tube flange by the screws which attach the flanges together. The leg preferably includes spaced walls which receive a portion of the ring therebetween and provide clearance to allow for movement of the tube as a result of thermal expansion.
