Abstract
A fastener for removably attaching a speaker grill to a cabinet includes a head having a pair of outwardly directed wings that have inwardly directed ramps at their bottoms to aid in disengaging the speaker grille receptacle from the fastener. A pair of angled abutments beneath the head are arranged to sandwich the receptacle between the abutments and the ramps to provide a secure, yet readily removable, grill. The tree-like base of the fastener includes a plurality of resilient branches for frictionally engaging the inner surface of an aperture in a wood or wood composition cabinet. The end of the base includes a pair of resilient wings that expand to engage the bottom of an aperture in a plastic cabinet.

A method of removably securing a push-on, pull-off decorative speaker grille to a cabinet comprising:
- forming a plurality of receptacles in the grille;
- providing a corresponding plurality of fasteners, each having a head with outwardly flared resilient wings for engagement with a corresponding receptacle and a tree-like base for securely engaging a corresponding suitable aperture in the cabinet;
- and
- dimensioning the heads of the fasteners and the receptacles such that a first pushing force is required for engagement and a second, larger pulling force is required for disengagement.
