- 12 - ABSTRACT OF THE DISCLOSURE A method of joining an object to an article is disclosed. In the method, a force accepting shoulder is formed on the object so as to have both a first surface for engaging a surface formed on the article and a second surface spaced away from the first surface. A force applying structure is formed on the article so as to have both a first surface for engaging the first surface of the force accepting shoulder of the object and a plurality of deformable tabs extending away from the first surface of the article. The tabs have a length dimension greater than the distance between the first and second surfaces of the object. The tabs also have small deformed areas on at least some of them. The first surfaces of the object and the article are brought into contact with one another and through this action at least an upper portion of the defor- mable tabs of the article are located in proximity to the second surface of the object. The deformations in some of the plurality of tabs extend out of the plane of the tabs in a direction away from the second surface of the article in proximity to which the tabs are located. The upper portion of the deformable tabs are bent into engagement with the second surface of the object. In this manner, the article and the object are joined and the tabs of the article which have the small deformed areas therein provide an added degree of rigidity to the joining of the article and the object.
