The invention relates to a system for retaining a component to a surface which includes a surface; a component; and at least two elements. Each element has a base connected to the surface, the at least two elements provide means for retaining the component to the surface, wherein a first means is biased to a first position in which the first means extend beyond an edge of a first base such that when the component is placed on the surface the first means are configured to move to a second position in order to retain the component in its position relative to the surface. The component provides at least one cavity defined by at least two inner faces, and wherein upon placement of the component on the surface, the base of each element is situated solely within the at least one cavity of the component.
