Abstract: The invention provides a connecting device for releasably connecting two objects, comprising a base plate fixedly attachable to the first of the objects and at least one projection extending therefrom so as to cooperate with receiving means located on the second object, characterised in that the projection is releasably mounted on the base plate via interengaging means. This arrangement allows accurate and secure alignment of the base plate at any convenient time up to connection of the two objects, particularly during formation or immediately after formation of the first object. The projection can be attached at any subsequent convenient time which means that the first object can be stored, transported and handled without the projection attached. This makes storage, transportation and handling easy and economical. The connecting device is particularly suitable for mounting cladding panels on a framework.
