The tube (5) fits over the outside diameter of the adaptor and lies with its endface (6) against the face of the element (1) or to a face on the adaptor A bolt (9) with head (11) is used to secure a spring plate (14) against the end (13) of the adaptor. A plate (12) I mounted behind the spring plate and supports it. The outside diameter of the spring plate is slightly larger than th bore of the tube so that the spring plate will be bent when the tube fits over it
