Abstract: A stiff and resilient body is provided including a pair of upstanding arm portions having upper and lower ends. At least the upper ends of the arm portions are upwardly divergent in the static conditions thereof and the lower ends of the arms are joined together by a suspension structure for suspending a selected article therefrom. The upper ends of the arms include integral downwardly and oppositely outwardly inclined catch flanges supported therefrom with each arm upper end and the associated catch flange defining a downwardly opening channel on the outer side of the corresponding arm remote from the other arm upper end. The catch flanges are relatively downwardly divergent and include remote upwardly convergent outer side wedge surfaces for camming the upper ends of the arms toward each other as the clip is upwardly displaced between spaced flanges of a bar joist from therebelow to a level with the lower ends of the catch flanges disposed above the upper marginal edges of the flanges.
