A fixing for mounting an operating unit (1) on a supporting structure (2) consists of a peg (11) of a relatively frangible material engaging with an aperture in the supporting structure, and has a support (3) with a replacement peg (31) with fastenings which fits onto the base of the main peg in the event of breakage. The replacement peg (31) is hollow and conical in shape, and it can be fitted with a rubber or plastic adapter ring (6) before engaging with the aperture in the supporting structure to take up play and prevent vibrations. The fastenings consist of screws (51, 52, 53) engaging with holes (41, 42, 43) in the end wall (100) of the radiator. The replacement support, peg and end wall are made e.g. from injected thermoplastic.</p> |
