Abstract

This support and retention device, which is easy to install, extremely safe and structurally efficient and has low costs, comprises, for each bar, a pair of uprights including each a box-like structure; an upper through seat in the box-like structure for receiving therein a different end of the bar; a bolt at the seat for locking the bar to the box-like structure; a resting foot pivoted to the box-like structure; a slidable plate accommodated inside the box-like structure, movable substantially vertically and having a lower folded end protruding from the box-like structure for engaging an undercut profile of the vehicle bodywork; and an oscillatable element pivoted inside the box-like structure and controlled by the head of a screw engaging in one end portion of a transverse tension element extending between the pair of uprights of structural and mechanical connection thereof. The oscillatable element engages a portion of the slidable plate so that, by tightening the screw, first the uprights are caused to slide along the bar for mutual positioning thereof, then, upon locking the uprights to the bar through the bolts, the slidable plates are subjected to vertical traction and engage with their end of undercuts of the vehicle bodywork.
