An attachment (24) has two spaced apart holder surfaces (38,40) each with an opening. The attachment is on the pivoting bonnet (16) or on the main body of the chassis (12). A rod assembly (22) on the bonnet or chassis has two end parts (30,32) of differing length. In an intermediate position of the pivoting part, the shorter end part (32) is inserted into, and removed from, the opening (44) of the appropriate holder surface (40), or the holder surface is slid onto and from the shorter end part. The shorter end part may have, at least, one radially protruding bolt element (34), and the holder surface may have, at least, one radial slot (46) corresponding to the bolt element. |
