         3 . The workbench according to  claim 2  wherein the positioning device includes a collar mounted on the stand in a sliding manner between a first position wherein it is received in the recesses and a second position where it is outside the recesses.  
     
     
         4 . The workbench according to  claim 3  wherein the collar includes two protrusions for insertion in the recesses of the plates of the neck of the rack.  
     
     
         5 . The workbench according to  claim 2  wherein the positioning device includes a collar mounted on the stand and a ring mounted on the collar and formed with two protrusions each for insertion in the recess of one of the plates of the neck of the rack.  
     
     
         6 . The workbench according to  claim 3  wherein the positioning device includes a spring compressed between the collar and the stand.  
     
     
         7 . The workbench according to  claim 3  wherein the positioning device includes a spring compressed between the collar and a stop formed on the stand.  
     
     
         8 . The workbench according to  claim 3  wherein the positioning device includes: 
 a cap including a stop formed thereon, wherein the cap is mounted on the stand; and  
 a spring mounted on the cap and compressed between the collar and the stop.  
 
     
     
         9 . A workbench including: 
 a stand;    a rack mounted on the stand; and    a clamping device mounted on the rack.    
     
     
         10 . The workbench according to  claim 9  wherein the clamping device includes a first jaw mounted on the rack and a second jaw mounted on the rack in a sliding manner.  
     
     
         11 . The workbench according to  claim 10  wherein the clamping device includes a beam telescopically inserted in the rack, and the second jaw is mounted on the beam.  
     
     
         12 . The workbench according to  claim 11  wherein the clamping device includes: 
 a bolt including a section formed with a thread and a section formed with a non-circular profile, wherein the bolt is rotationally mounted on the rack;  
 a mount secured to the beam, wherein the second jaw is secured to the mount; and  
 a paw including at least a tooth formed as a portion of a thread corresponding to that of the bolt, wherein the paw is pivotally mounted on the mount between a first position where the tooth is engaged with the thread of the bolt and a second position where the tooth is disengaged from the thread of the bolt.  
 
     
     
         13 . The workbench according to  claim 12  wherein the clamping device includes a spring mounted on the mount in order to force the paw to the first position.  
     
     
         14 . The workbench according to  claim 12  wherein the clamping device includes a handle connected with the bolt so that rotation of the handle causes rotation of the bolt but movement of the handle does not cause movement of the bolt.  
     
     
         15 . The workbench according to  claim 14  wherein the clamping device includes a controller mounted on the mount in a sliding manner between an idle position leaving the paw in the first position and a working position moving the paw to the second position.  
     
     
         16 . The workbench according to  claim 15  wherein the handle is connected with the controller so that movement of the handle causes movement of the controller but rotation of the handle does not cause rotation of the controller.  
     
     
         17 . The workbench according to  claim 16  wherein the clamping device includes a connector including a first end secured to the mount and a second end connected with the handle so that pulling of the handle does not cause pulling of the connector until the handle moves the paw to the second position via the controller.  
     
     
         18 . The workbench according to  claim 17  wherein the clamping device includes a spring connected between an end of the handle and an end of the connector so as to bias the handle in order to force the controller to the idle position.  
     
     
         19 . The workbench according to  claim 12  wherein the clamping device includes a controller mounted on the mount in a sliding manner between an idle position leaving the paw in the first position and a working position moving the paw to the second position.  
     
     
         20 . The workbench according to  claim 19  wherein the clamping device includes a handle connected with the controller so that movement of the handle causes movement of the controller but rotation of the handle does not cause rotation of the controller.  
     
     
         21 . The workbench according to  claim 20  wherein the handle is connected with the bolt so that rotation of the handle causes rotation of the bolt but movement of the handle does not cause movement of the bolt.  
     
     
         22 . The workbench according to  claim 21  wherein the clamping device includes a connector including a first end secured to the mount and a second end connected with the handle so that pulling of the handle does not cause pulling of the connector until the handle moves the paw to the second position via the controller.  
     
     
         23 . The workbench according to  claim 22  wherein the clamping device includes a spring connected between an end of the handle and an end of the connector so as to bias the handle in order to force the controller to the idle position.
