Abstract
Abstract A latching mechanism for affixing a first item to a second item includes a male latching portion affixed to the first item, and a cavity defined within the second item disposed to receive the male latching portion. The male latching portion includes a tongue affixed to, and extending outward from, the surface of the end of the first item that is to abut the surface of the end of the second item when the first item is affixed to the second item. The tongue of the male latching portion defines a spring finger therewithin having one end thereof affixed to the end of the tongue closest to the surface of the end of the first item and extends outward therefrom surrounded by the sides and end of the tongue. The spring finger has at its free end a locking tooth that extends downward from the tongue to be captured within the cavity of the second item.
