Abstract
Abstract A tool for forming a depression in a strap of material which is disclosed to comprise a C-clamp base, a reaction cup on one arm of the C-clamp base and a bolt-like deforming member threadedly mounted through the other arm of the C-clamp base. A bearing is provided at the head of the bolt to facilitate deformation and locator means are provided on the base of the clamp to gauge the distance of the depression from the edge of the material in which the depression is to be formed.
