| 11. A device for attaching a guide rail to a substrate comprising:
support means adapted to attach the guide rail to a substrate;
a moveable part attached to said support means;
a flexible element floatingly supporting said moveable part; and
a stop adjacent said moveable part whereby when the guide rail is attached to the substrate by said support means and a deforming
force is applied to the guide rail moving the guide rail and said moveable part in a deforming direction, said flexible element
deforms until the deforming force exceeds a predetermined limit whereupon said stop engages said moveable part and prevents
further movement of the guide rail in the deforming direction, wherein said moveable part includes a top strip unit adapted
to engage the guide rail and said flexible element includes at least one flexible strip unit retained between said top strip
unit and said stop, wherein the deforming direction includes alone a height axis of the guide rail, and wherein said top strip
unit is crescent shaped in profile with an apex line upon which a rail base of the guide rail is positioned.
