  "description_excerpt": "The present disclosure relates to a connecting assembly including first and second connectors, a method for manufacturing the connecting assembly, a vehicle body structure, and a method for assembling the vehicle body structure.\n\nVehicles, in particular, automobiles that are typically manufactured using mass-production techniques, are highly modularized. For example, there is trend to combine a common platform, which includes a chassis, with various upper body structures or so called “hats”. In order to further ease assembly of such vehicles, many substructures are pre-assembled before they become permanently fixed to each other. Thus, there is a need to optimize the pre-assembly process.\n\nGenerally, snap fit connectors are known as releasable connections. For example, U.S. Pat. No. 5,102,253 describes a snap fit device for releasably joining two parts, in which one part forms a plug and an opposite part forms a socket, and the parts are provided with male and female elastic snap fit structures. In a locked state, end faces of the parts are in contact with each other. A snap fit connector manufactured in a molding process is disclosed in U.S. Pat. No. 3,596,940.\n\nThe present disclosure provides improved solutions for releasably assembling two parts.\n\nTo this end, the present disclosure provides a connecting assembly including first and second connectors, a method for manufacturing the connecting assembly, a vehicle body structure, and a method for assembling the vehicle body structure.",
