ABSTRACT:
A clamp is provided which includes a buckle of high strength material with top, bottom, and side walls defining a rectangular passage. An elongate band is anchored at one end to the buckle and wrapped on itself and passed through the buckle at least twice to define a clamp structure for securing a hose on a conduit.
The top wall of the buckle has two integral but discrete locking tabs centrally located and adapted to be bent down about their lines of juncture with the top wall. A chisel-tipped punch is driven radially inward between the free ends of the tabs to force them into the adjacent layer of the band, causing band metal to flow and produce upset interlocks between the band and the tabs outward of the tabs. The ends of the tabs also cause band metal to flow into a bulge between the tabs. The punch tip divides the bulge and flows the metal toward the tab ends to produce a second pair of upset interlocks between the band and the tabs.
The inward movement of the punch and tabs also forms dimples in the layers of the band and these dimples are depressed into an aperture formed in the bottom wall of the buckle, thus producing a second lock against slippage of the band under high tension. The high strength of the tabs prevents the dimples from flattening out and thus preserves their locking ability.
