ABSTRACT:
A structure, which interlocks a relatively thin sheet of material with a relatively heavy member, for example, a hub member with a sheet metal fan structure, comprises the hub on one end having a groove dividing the hub into an inner sleeve-like shoulder having a length substantially greater than the thickness of the sheet-like member, the groove has a wider base than the throat adjacent a second outwardly extending shoulder on which the member rests. The sleeve is cut into a plurality of segments with alternate segments being deformed to force a portion of the edge of the sheet-like member into the groove to form a spline connection with the hub.
