A surgical device includes a first member, deformable to move a pair of opposing projections toward one another. The projections are received in a pair of opposing openings in a second member, so the first member can pivot relative to the second member about an axis defined by the projections. In another aspect, a surgical instrument includes a first pinless joint pivotably coupling a first jaw to a second jaw, a second pinless joint coupling a distal end of an actuating member to the first jaw, and a third pinless joint coupling a handle to a proximal end of the actuating member. The third pinless joint translates movement of the handle into axial movement of the actuating member, and the second pinless joint translates axial movement of the actuating member into pivotable movement of the first jaw relative to the second jaw about the first pinless joint.
