Abstract
Abstract A clamping band for hoses and other cylindrical objects consists of a flat metal strap having a repetitive pattern configuration to provide desired amounts of elastic and plastic stretch capability and a pawl and tooth connection for adjustably joining the ends of the strap. In all embodiments the strap includes apertures evenly distributed throughout the circumference of the band to achieve desired stress/strain characteristics. In certain embodiments the apertures comprise circular punched holes and the strap may further include transverse or circumferentially extending slits to form the desired pattern, suitable for high volume manufacturing techniques.

Claim 3
Dependent Claim
21 words
The clamp as set forth in claim 1 wherein said slots and apertures are defined by transversely extending straight line segments.
Claim 4
Dependent Claim
23 words
