ABSTRACT:
A holding element fastener formed of molded plastic for fastening within a support opening and having a base body and two resilient fingers for extending through the support opening. The fingers stand at an acute angle to each other, and when in the mounted condition grip behind the support opening. The base body and the resilient fingers define an approximately V-shape triangular inter-space and each of the resilient fingers is provided on its outer circumference with two inwardly extending open areas which reduce the total amount of plastic required and simplify the operation of molding the holding element fastener. The open areas are located on opposite sides of a laterally extending middle stay in the form of a relatively thin rib. The upper limit of each middle stay is defined by a separate transverse outwardly extending cross stay which joints to the upper end of the respective resilient finger and the associated middle stay.
