 a band having a band length, a band width, a bottom appendage-contacting surface, and a top surface and,   a retainer element disposed on said top surface of said band, said retainer element having a width that is less than or equal to said band width and a length that is less than or equal to said band length.   
     
     
         2 . The device of  claim 1  wherein the band comprises a hypoallergenic material. 
     
     
         3 . The device of  claim 1 , wherein said band comprises an adhesive material. 
     
     
         4 . The device of  claim 3 , wherein said band comprises an adhesive material on said bottom appendage-contacting surface. 
     
     
         5 . The device of  claim 1 , wherein said retainer element comprises a contoured dome-like shape as viewed from side to side. 
     
     
         6 . The device of  claim 1 , wherein said retainer element is symmetrically disposed about said band. 
     
     
         7 . The device of  claim 1 , wherein said band comprises synthetic material. 
     
     
         8 . The device of  claim 7 , wherein said synthetic material comprises plastic, rubber, or a combination thereof. 
     
     
         9 . The device of  claim 1 , wherein the band length is from 60 mm to 90 mm. 
     
     
         10 . The device of  claim 1 , wherein the band width is from 6.0 mm to 13 mm. 
     
     
         11 . The device of  claim 1 , wherein the band thickness is from 0.04 mm to 0.28 mM. 
     
     
         12 . The device of  claim 1 , wherein the retainer element has a dome-shaped upper contour, a length from 12.5 mm to 38 mm, a width from 3.0 mm to 12.7 mm, and a height of 0.2 mm to 1.3 mm. 
     
     
         13 . The device of  claim 1 , wherein said device comprises a non-skid material. 
     
     
         14 . The device of  claim 1 , wherein said retainer element comprises a plurality of discontinuous sub-elements disposed on said band. 
     
     
         15 . The device of  claim 1 , wherein the ratio of the height of the retainer element measured from the surface of the band upon which it is disposed and the total height of the retainer element and the band (exclusive of adhesive) is in the range of 0.2 to 0.9. 
     
     
         16 . The device of  claim 1 , wherein the ratio of the ratio of the length of the retainer element, and the length the band is in the range of 0.15 to 0.6. 
     
     
         17 . The device of  claim 1 , wherein the ratio of the width of the retainer element to the width the band is in the range of 0.2 to 1.3. 
     
     
         18 . The device of  claim 1 , further comprising a component to secure the device on said appendage, said component selected from the group consisting of a clasp, Velcro, a button, a buckle, a snap, an elastic material, and any combination thereof.
