A fastening device of the type having a stem, toggle arms at the opposite end of the stem, extending outwardly from an extended axis of the stem, a toggle hinge forming a part of the toggle arms and connecting the toggle arms to the stem and elastically biasing the toggle arms in the extended position. The toggle arms are pivotable about the toggle hinge to a closed position extending substantially parallel with the extended axis of the stem. A strap extends across the extended axis of the stem between the extremities of the toggle arms to maintain the toggle arms in the extended position. The extremities of the strap and the toggle arms are connected and a mid-hinge is formed centrally of the strap at the extended axis of the stem so that the portions of the strap on either side of the mid-hinge may pivot about the hinge to move the toggle arms and strap portions to the closed position. Resilient biasing means extend between the strap and toggle arms at positions inwardly displaced from the connections between the extremities of the strap and toggle arms and retain the strap away from the toggle arms with the mid-hinge disposed at or over center and forcing the strap back over center from the closed position. The stem of the fastener is provided with vertical slots to receive portions of the mass of the stem under deformation.
