With reference to Figure 3 the present invention relates to a method of manufacture of a product from a first component (4) of deformable material and a second component (5), the method comprising the steps of:

inserting a portion of the first component (4) through an aperture predefined in the second component (5); and subsequently
deforming the material of the first component (4) to form a pair of spaced apart shoulders (50) integral with the first component (4), the spaced apart shoulders (50) holding therebetween the second component (5) and thereby preventing the second component (5) sliding along the first component (4); wherein:
each shoulder (50) is formed by applying tool means (20, 21) to a surface of the first component (4) to create a recess in the surface and to form the shoulder (50) adjacent to the recess with the shoulder (50) being formed by displacement of the deformable material of the first component (4) during the creation of the recess.

The present invention also relates to apparatus for performing the method.
