A spring clip for attaching a radiant burner unit to a cooktop includes a retention tab having a portion extending in a first direction and a retention arm defining a lever portion projecting away from the retention tab to an end displaced from the tab in a second direction generally normal to the first direction. The retention arm further defines a resiliently deformable section facilitating movement of the lever toward and away from the retention tab. The spring clip further includes a snap tab positioned opposite the retention arm from the retention tab and resiliently deflectable toward and away from the retention tab.
