Toothed seal for hard thermoplastic strap

摘要

A seal is provided for joining a pair of overlapping plastic strap portions. The seal includes a body of sheet material having a strap engaging surface which engages the strap portions when the seal is closed about the strap portions. The body has a plurality of teeth projecting from the strap-engaging surface. Each tooth is formed of material displaced outwardly from the strap-engaging surface to define a recess therein. Each tooth has a solid configuration defined by converging side surfaces and truncated along a top surface.
