Abstract
A fastener is formed monolithically, or as a one-piece structure, for example 100% plastic. The fastener includes a body having first and second portions on respective sides of a positioning wall or stop means. A first portion includes a plurality of compressible retention surfaces separated from adjacent retention surfaces by a corresponding conical structure and a cylindrical surface on the body. A second portion includes a plurality of resiliently flexible tongues spaced apart from each other. The tongues may be positioned on opposite sides of the body from each other, and/or at different axial positions along the body.
