Push clip fastener with retention tabs

A motor vehicle fan shroud comprising:

• a first shroud portion engaging a radiator of the motor vehicle;
• a second shroud portion engaging the first shroud portion;
• a receiving member integral with one of the first shroud portion and the second shroud portion having an aperture and having a predetermined material thickness between a front surface and a back surface;
• and
• a clip member integral with the other of the first shroud portion and the second shroud portion having a base surface, having a pair of substantially parallel tangs projecting outwardly from the base surface and each tang having an engaging barb and the tangs disposed in part within the aperture with barb engagement surfaces engaging the back surface, having a pair of cantilevered spring tabs each with a tab engaging surface engaging the front surface and adjacent the tangs and extending from the base surface substantially parallel thereto, the tab engaging surface defining a distance to the barb engagement surfaces in a unassembled condition less than the thickness of the receiving member,
• wherein, when the clip member is pressed into the aperture in the receiving member, the tangs are bent as the barbs enter through the front surface, the engaging surfaces of the spring tabs initially engage the front surfaces of the receiving member before the barbs exit this aperture at the rear surface, the spring tabs are deflected after initial engagement as the barbs move through the aperture and develop a spring load between the first shroud portion and the second shroud portion, and the tangs snap back after the barbs exit the aperture at the rear surface to engage the rear surface, thereby positively retaining the receiving member and maintaining the spring load between the first shroud portion and the second shroud portion.
