An ear projects outwardly between the apertures and an elongated slot in the overlapping portion. The lapped portion includes a plurality of openings, each having an outwardly projecting hook. The hooks and projections are geometrically shaped to, upon engagement with one another, laterally center the lapped and lapping portions and interlock the portions to one another. The lapped portion includes an outwardly projecting protuberance engageable in the slot of the lapping portion to guide the portions for longitudinal and laterally constrained movement. The ear has parallel sides and lobes projecting outwardly from the sides, forming a purchase for the jaws of a crimping tool, preventing the tool from slipping from the ear. Upon interlocking the hooks and projections, the ear is crimped to secure the clamp about the parts. | |
