<p>The assembly has cross-bars (100) whose ends are supported at an assembling end on a face (210) directed towards the interior of a frame (C) on ends of a post (200). A stopper (300) includes a body projecting from an internal support surface towards a hollow core of the post at a positioning and assembling end of the stopper. A head is preformed, so that direct curve of a cylindrical side surface withdraws a profile section of the end part of the post when the stopper is stopped. An external surface of the head is preformed to form a surface section of the cross-bars. The stopper is made of noryl type polymeric alloy.</p> |
