ABSTRACT:
A two-part latch comprising hinged bail and crank for latching a globe and ring assembly to a fixed housing requires no screws, rivets or similar discrete fastening means. The crank member is a rectangular link formed from a length of resilient wire having its ends butted together at a split near the middle of one side. It is inserted into a captivating recess in which a pair of side ramps and a cut-off center ramp engage opposite faces of the link and cause the portions on each side of the split to twist and snap back after passing beyond the cut-off, whereby the crank is permanently captivated in a hinged attachment.
