MOBILE FIXING
An anchor device for fixing a roof panel or similar planar body to a substrate in a mobile manner includes a first part (1) having a substantially planar body section (2) that has an anchor portion (3) protruding from it. The anchor portion (3) allows the first part (1) to be secured to a substrate. A second part (7) also has a substantially planar body section having an aperture (8) in the middle through which the anchor portion (3) of the first part (1) can pass. The relative dimensions of the anchor portion (3) and the aperture (8) are such that the second part can move laterally with respect to the first part. The second part is secured, in use, to a roof panel or the like.
