A band clamp comprising a sleeve and a tightening mechanism that includes at least one fastener, such as a nut and bolt, as well as a reaction member which is constructed of a single piece of sheet metal. The reaction member is disposed between the end flanges of the clamp sleeve and can be shaped such that it is forcibly pressed into engagement with the underlying pipe when the clamp is tightened. The reaction member can be a separate component retained between the flanges by engagement of end portions of the reaction member with retainer ears on the flanges. Alternatively, the end flanges and reaction member can all be unitary portions of the clamp sleeve such that the complete band clamp, except for the bolt and nut, is comprised of a unitary piece of sheet metal.

The invention claimed is: 1. A band clamp, comprising: a band that extends from a first end to a second end; and a tightening mechanism located at said first and second ends and including a first end flange, a second end flange, and a reaction member, wherein said first and second end flanges are f
The invention claimed is: 1. A band clamp, comprising: a band that extends from a first end to a second end; and a tightening mechanism located at said first and second ends and including a first end flange, a second end flange, and a reaction member, wherein said first and second end flanges are formed at said first and second ends, respectively, and said reaction member lies between said flanges and is v-shaped with first and second extending legs; whereby, during tightening said first and second end flanges are drawn toward each other and said first and second extending legs are also drawn toward each other. 2. The band clamp of claim 1, wherein said tightening mechanism further comprises a bolt and a nut, and wherein said bolt extends through holes in said flanges and reaction member and ends at said nut. 3. The band clamp of claim 1, wherein said band is a round sleeve and said first and second end flanges extend radially from said band and are unitary therewith. 4. A band clamp, comprising: a band that extends from a first end to a second end; and a tightening mechanism located at said first and second ends and including a first end flange, a second end flange, and a reaction member, wherein said first and second end flanges are formed at said first and second ends, respectively, and said reaction member lies between said flanges and is v-shaped with first and second extending legs; whereby, during tightening said first and second end flanges are drawn toward each other and said first and second extending legs are also drawn toward each other; wherein each, of said first and second end flanges terminate in a pair of retainer ears spaced-apart to define a keeper notch therebetween. 5. The bend clamp of claim 4, wherein each of said first and second extending legs have a hanger ear formed in an end of said leg, said hanger ears extend transversely away from each other and are each disposed in one of said keeper notches. 6. The band clamp of claim 1, wherein said first and second extending legs intersect at a base of the reaction member, and wherein said first and second flanges each engage an upper end of said first and second legs, respectively, such that said base moves radially inwardly toward a central region of the clamp during tightening of the tightening mechanism. 7. A band clamp, comprising: a band that extends from a first end to a second end; and a tightening mechanism located at said first and second ends and including a first end flange, a second end flange, and a reaction member, wherein maid first and second end flanges are formed at said first and second ends, respectively, and said reaction member lies between said flanges and is v-shaped with first and second extending legs; whereby, during tightening said first and second end flanges are drawn toward each other and said first and second extending legs are also drawn toward each other; wherein each of said first and second end flanges have a rib formed therein that extends from the lower end of each flange and onto respective first and second ends of said band. 8. The band clamp of claim 7, wherein said reaction member further has a support plate for each rib, said support plate being located at an intersection of said first and second extending legs and being aligned with said ribs. 9. The band clamp of claim 8, wherein each of said first and second end flanges have a retainer ear formed on their outer ends. 10. The band clamp of claim 8, wherein said first extending leg of said reaction member is unitary with said first end flange and wherein said second end flange has a retainer ear formed on its outer end. 11. A band clamp, comprising: a band that includes a roundish sleeve having a central region; a tightening mechanism that is partly formed from said sleeve, comprising: a first end flange and a second end flange that both generally extend radially from said sleeve; a reaction member that lies between said first and second end flanges, wherein said reaction member includes a base and first and second extending legs, said extending legs being joined at said base and extending divergently from said base and from the other extending leg to outer ends of said flanges; and a fastener; wherein, when the band clamp is tightened using said fastener, said reaction member is deformed to a narrower width and said base moves inwardly toward a central region of said band. 12. The band clamp of claim 11, wherein said fastener comprises a bolt and a nut, and wherein said bolt extends through holes in said flanges and reaction member and ends at said nut. 13. The band clamp of claim 11, wherein each of said first and second end flanges terminate in a pair of retainer ears spaced-apart to define a keeper notch therebetween. 14. The band clamp of claim 13, wherein each of said first and second extending legs have a hanger ear formed in an end of said leg, said hanger ears extend transversely away from each other and are each disposed in one of said keeper notches. 15. A band clamp, comprising: a band that includes a roundish sleeve having a central resign: a tightening mechanism that is partly formed from said sleeve, comprising: a first end flange and a second end flange that both generally extend radially from said sleeve; and a reaction member that lies between said first and second end flanges, wherein said reaction member is v-shaped with a base that joins first and second extending legs; whereby, when the band damn is tightened, said reaction member is deformed to a narrower width and said base moves inwardly toward a central region of said band; wherein each of said first and second end flanges have a rib formed therein that extends from the lower end of each flange and onto said sleeve. 16. The band clamp of claim 15, wherein each of said ribs form a recess in the interior surface of said sleeve. 17. The band clamp of claim 16, wherein said reaction member further has a support plate for each formed recess, said support plate i) extends from said base, ii) Is aligned with said respective recess, and iii) is adapted to complement the shape of said recess. 18. The band clamp of claim 17, wherein each of said first and second end flanges have a retainer ear formed on their outer ends. 19. The band clamp of claim 17, wherein said first extending leg of said reaction member is unitary with said first end flange and wherein said second end flange has a retainer ear formed on its outer end. 20. A band clamp comprising: a band having a roundish sleeve terminating in first and second open ends; and a tightening mechanism located at said open ends and comprising: a first end flange that extends radially from said first open end and is unitary therewith; a second end flange that extends radially from said second open end and is unitary therewith; a reaction member generally located between said end flanges, said reaction member comprising a base and unitary first and second legs, wherein said first leg extends radially outwardly from said base to an outer end of said first end flange and said second leg extends radially outwardly from said base from the first leg has been to an outer end of said second end flange; and a fastener that extends through holes formed in said tightening mechanism; wherein said extending legs connect to said end flanges only at the outer ends of said end flanges such that, during tightening of the band clamp using said fastener, said first and second end flanges are drawn towards each other, thereby forcing said legs towards each other with said base moving inwardly toward a central region of said sleeve.
