Apparatus for the rapid twist-tying of a wire ceiling hanger onto a ceiling joist, comprising easily bendable wire of U-shape with a relatively longer leg and a relatively shorter leg having their respective axes in a common plane and radially spaced for straddling the joist, the apparatus comprising an axially rotatable handle slidably engaging the joist-straddling wire hanger by the longer of its legs and radially inward of the hanger shorter leg, and pivotally mounted on the handle a fork adapted to capture the shorter hanger leg for helical movement around and toward the hanger longer leg responsive to simultaneous rotation and axial displacement of the handle relative to the joist, whereby the captured shorter leg is wrapped around the hanger longer leg freely of the handle.
