This invention relates to vehicles having parts connected with a sealing spring fastener, which comprises a U-shaped structure, on which an elastic body has been incorporated. The elastic body has a hermetically closed cavity within the U-shaped structure. The sealing spring fastener can form an assembly with an extension of a panel, preferably a plastic panel. The assembly or the fastener by itself can be engaged into the slot of a solid sheet, preferably a metal sheet, in a manner that one side of the sheet is sealed from the other side of the sheet in the vicinity of the slot. In a preferred version, the sealing fastener comprises a substantially non-elastic tough casing around portion of the elastic body in order to avoid rapture during insertion of the fastener into the slot.

This invention relates to a spring fastener, which comprises engagement springs in opposite sides of the fastener. Each engagement spring has an engagement region comprising a hindrance portion, which increases considerably the removal to insertion force ratio as compared to such ratio in the absence of the hindrance portion, thus permitting very easy insertion with considerably more difficult removal of the fastener from the slot of a panel, which provides an efficient ergonomically balanced removal to insertion force ratio. The hindrance portion comprises ripples or other hindrance elements of unexpectedly minute dimensions for providing this efficient ergonomic force balance.

This invention pertains fasteners which are characterized by adaptability of use with substrates, such as steel panels for example, of various thicknesses. This is achieved predominately by providing the fastener with legs having an origin section in the vicinity of the head of the fastener. Expansion promoters and/or anti-sliding elements improve considerably the separation resistance of objects connected with the fasteners of the present invention. Assemblies and vehicles comprising the spring fasteners of this invention, connecting two objects, one of the objects comprising a slot in which the fastener is inserted, and the other a hole, are also included within the scope of the instant invention. Provision of an elastic body in the vicinity of the bottom section of the fasteners provides water and gas proof properties, and further assist in the elimination of squeaking noises.
