  • Patent number: 5068945
    Abstract: A fastener particularly adapted for securing an end of a cord in an opening in an object comprises a cylindrical shaped body. Extending through the fastener body is a passageway to hold an end of the cord, for example. In practice, the fastener preferably is made of plastic allowing the fastener to be molded onto the cord. Projecting outwardly on an angle from an inner end of the fastener body is an ear. Because the cord, the fastener ear, or both are flexible, the fastener ear and cord may be pressed into alignment. Once aligned, the fastener and cord end may be threaded through the opening in the object with the ear then returning to its prior nonaligned position. The cord is prohibited from being drawn back through the opening by an interference fit between the fastener ear and the object.
