A method of securing a second object to a first object, the method comprising the steps of: - providing the first object comprising an attachment face; - providing the second object with a generally flat sheet portion; - providing a connector, the connector comprising a thermoplastic material in a solid state; - placing the second object relative to the first object so that the sheet portion lies against the attachment face and a protruding section of the sheet portion extends into an opening of the first object, the opening having a mouth in the attachment face, the protruding section extending through the mouth into the opening; - while the protruding section extends into the opening, causing energy to impinge on the connector while the connector is placed relative to the first and second objects and extends through the mouth into the opening, until a flow portion of the thermoplastic material becomes flowable and flows relative to the first object and relative to the protruding section; and - causing the flow portion to resolidify; - wherein the resolidified flow portion locks the protruding section relative to the opening. |
