         2 . The punching device according to  claim 1 , wherein said adaptation comprises: a stretchable outer wall ( 21 ) and a non-stretchable inner wall ( 25 ). 
     
     
         3 . The punching device according to  claim 1 , wherein said connector is in a form of plurality of hooks ( 30 ) connected to opposite edges of said sleeve ( 11 ), and a string ( 29 ) threaded through said hooks ( 30 ), thereby pulling said string results with fastening said connector. 
     
     
         4 . The punching device according to  claim 1 , wherein said sleeve ( 11 ) comprises:
 a plurality of inflatable cells ( 26 ) arranged in a matrix form,   wherein each of two adjacent of said cells ( 26 ) having an air passage ( 27 ) therebetween, and   thereby upon hitting one of said cells, air of said cell is evenly distributed in the surrounding cells thereof.   
     
     
         5 . The device according to  claim 1 , wherein said sleeve ( 11 ) comprises a plurality of loops ( 12 ) at the upper and lower edges thereof, for allowing threading therein a fastener. 
     
     
         6 . The device according to  claim 1 , wherein an outer layer of said sleeve ( 11 ) comprises a leather or leather-like material. 
     
     
         7 . The device according to  claim 1 , further comprising at least one spongy layer, for softening a hit thereon. 
     
     
         8 . The device according to  claim 1 , wherein an inner layer ( 25 ) of said sleeve ( 11 ) comprises a rough fabric, for increasing a grip of said sleeve to said pole ( 17 ). 
     
     
         9 . The device according to  claim 8 , wherein said fabric is jute. 
     
     
         10 . The device according to  claim 1 , wherein said sleeve ( 11 ) comprises rubber. 
     
     
         11 . The device according to  claim 1 , wherein said sleeve ( 11 ) comprises attaching means to a pillar, for allowing a single user to tie said device around said pillar even if a circumference of said pillar is greater than said user can surround. 
     
     
         12 . The device according to  claim 11 , wherein said attaching means is a Velcro fastener. 
     
     
         13 . The device according to  claim 11 , wherein said attaching means is a magnet. 
     
     
         14 . The device according to  claim 1 , wherein said inflatable sleeve comprises a snap-release valve, for instantly releasing air from said inflatable sleeve.
