Abstract
A fastener which can be economically made for securing parts to metal framing (e.g. channel framing) having side flanges with inwardly turned, hook-shaped lips defining a slot therebetween. The fastener comprises an elongate body having inside and outside faces, opposite sides and opposite ends, a width less than that of the slot and a length greater than the width of the slot. The fastener also includes a carrier constituting an elongate platform having inside and outside faces, opposite sides and opposite ends. The body is mounted on the outside face with means for rotatably mounting the body. The platform is suspended in the slot on resilient non-linear arms which increase in effective length when stressed by an effective inward force permitting the body to be rotated into generally crosswise position relative to the slot and tending to draw the body into clamping engagement with the lips of the framing.
