<p>The handle fixing is made from a metal blank which is rolled into a tubular sleeve (4) into which the handle (2) is fitted. Each of the two facing edges (7,8) of the sleeve have a part forming a locking key (11) in the form of a dovetail which prevents the edges from moving tangentially. Inside the sleeve are longitudinal ribs angularly divided on its internal periphery. In the thickness of these ribs the sleeve is tapped to allow fastening the handle.</p> |
