This invention pertains fasteners, and more particularly fasteners which have expandable legs and which attach one object to another object. It also pertains combinations of one or more objects with said fastener(s), parts or objects connected with the fastener(s), as well as vehicles comprising parts connected with said fastener(s). The fastener comprises a substantially flat head and two expandable legs. The head preferably has an upper side and a lower side, preferably separated by a gap. The head also has a hole (round, oblong or otherwise shaped) in which the expanding body may engage or pass through for expanding the legs and securing a first object having a slot to a second object having a hole, such as a metal sheet to a plastic panel, for example. The fastener also comprises a Y-shaped funnel configuration, which has been formed by a partial cut of the legs. The sides of the Y-shaped funnel comprise inwardly bent portions which are designed to extend into the slot of the first object. Further, the fastener of the present invention may comprise an elastic body at least under the head. This invention also relates to vehicles comprising parts connected by the fasteners of this invention. A large number of advantages are derived from the critical configuration of the funnel of the present invention, which produces jamming and clamping of the expanding member within the slot into which the fastener is inserted, resulting to highly improved pulling force. In addition, the fastener of the present invention may be used in slots of different widths without any problems of rattling noises. Further, the fastener of this invention may be pulled easily out of the slot, if so desired, in contrast with the fasteners of the present state in the art, which are destroyed when pulled, due to the barbs been presently utilized.
