A resilient element, for example a clip (16, 17), a method of producing this element and a mould for the production of the resilient element. The resilient element is of plastic and its resilience is obtained by casting the plastic in a mould (1, 2) in which the opposite walls of the mould cavity in the area (15) which is intended to impart resilient properties to the element are held at different temperatures during the solidification of the plastic material. Only after the element being taken out of the mould does it receive its final shape. Shrinkage of material is here utilized actively to impart the resilient properties to the element. |
