Abstract: It consists of a cylindrical tube carrying a spring inside with a hook on one end to engage the fixed trunk hasp and a ring or closed loop on the other end to be lockably engaged by the trunk latching mechanism usually carried on the trunk lid. Once the hook is engaged with the fixed ring of the trunk, the lower end of the tube is manipulated so that a pair of opposed slots in the lower end of the wall of the tube engage upon the ring or hasp of the trunk so that the spring is under relatively heavy tension and thus acts as a substantially rigid link when the trunk lid is closed and locked upon the other end of the spring.
