Abstract

A heater core is mounted over an opening in a wall of a heater and air conditioner case and secured by a single spring steel strap having a straight portion extending parallel to the tubes of the core and bearing on the header flanges. The strap has terminal hook portions which engage anchor apertures in the web outboard of the core. The apertures have flanged edges for engagement by the hook portions and the strap is manually flexed for engagement or disengagement of the hook portions during installation or removal of the strap so that no tools are required. One embodiment has a hook on one end of the strap and a snap fastener on the other end. Another embodiment has identical hooks on both ends of the strap.
