Abstract: A spring fastener for supporting circuit components or the like to a mounting surface. The fastener consists of a length of resilient wire bent into a pair of arms extending from both sides of a U-shaped base so as to be substantially normal thereto. Lower arm sections are disposed in spaced diverging relation in a common plane while upper arm sections extend in converging relation crossing each other in scissors-like fashion adjacent their midportion. The arms terminate in retainer legs spaced to receive the component with the legs located in a plane substantially parallel to the plane of the U-shaped base. The crossed upper sections change angularity by scissors-like movement to urge the component into retaining engagement with the support panel to compensate for variations in dimensions of the component.
