The hook (6) widens starting at its tip and is provided on its backside with a slanted surface (7) cooperating with a corresponding bevel (23) at the tool in order that, after the engagement between hook and cross-pipe (21) and further pivoting of the support frame (4), this support frame be automatically centered until it is locked with respect to the tool.
