A fixture for rapidly and precisely mounting uniquely-shaped work-pieces in machine tools, incorporates a U-shaped member whose bight is fixed to the fixture and whose upright legs constitute levers on the free ends of which are formed lateral outside and inside surfaces. The outside surfaces engage the work-pieces; the inside surfaces, convex in the vertical direction, are engaged by an operator to move the lever free ends outwards to engage the work-pieces. The operator is a vertical cone, driven axially by a bolt fixed to it and threaded into the fixture through the bight. The U-shaped member may be seated in a well on the fixture, and cut-outs on the surfaces of the fixture and the lever free ends have edges complementary to the work pieces and receive the work-pieces prior to being fixed on the fixture. In an alternative embodiment, the outside surfaces of the lever free ends my engage the inside of a work-piece to fix it on the fixture.
