An air conditioning unit is provided which includes an outdoor section, which has a condenser coil mounted therein and an outer protective housing partially enclosing the outdoor section. The housing has a substantially rectangular opening therein in overlying relation with the condenser coil. The opening is defined by at least two spaced parallel coplanar wall sections, each of which has a predetermined width. A flexible protective grille, which is configured to substantially cover the rectangular opening, has two edges thereof which are spaced from one another by a distance substantially equal to the spacing of the wall sections. Each of the edges have integrally formed therewith two or more narrow, rigid, spaced apart extensions, which project perpendicularly therefrom. Each of the narrow extensions has a length less than the predetermined width of the wall sections. Each of the wall sections is provided with conformations, which are formed at locations corresponding to the location of each of the narrow extensions. The conformations are configured to mechanically receive and retain the narrow extensions, which are formed on a first edge of the grille without flexing of the grille. The narrow extensions on the second edge of the grille are thereafter mechanically received and retained with their respective retaining conformations upon flexing of the grille. Following assembly of the extensions on the second edge of the grille, the grille returns to its undeformed condition and is then thereby positively mounted in the opening.
