ABSTRACT:
A tube-to-plate connection includes a plate defining an aperture where the tube is to be attached to the plate. The portion of the plate surrounding the aperture includes a plurality of fingers extending away from the plane of the plate and projecting radially inwardly toward the axis of the aperture. The end of the tube lies generally against the radially inward projections of the fingers to prevent movement of the tube longitudinally further through the plate. The tube side wall includes a radially deformed portion adjacent each finger to prevent rotation of the tube in the plate. The fingers and the tube end include portions adjacent the radially inward projections of the fingers which are flared radially outward to prevent movement of the tube longitudinally out of engagement with the plate.
