Claim:
An assembly for covering a grille of an air conditioning vent to completely block air flow, comprising: (a) a rigid or semi-rigid plastic cover, wherein said cover has a compressible foam along its perimeter for creating an air-tight seal between said cover and a vent area including said grille and wherein there are two small holes in the center area of said cover; (b) an elastic cord having an eyelet forming a looped end and a free end, wherein said looped end has an adjustable size and has two hooks having a first end freely slidable on said looped end and a second end opposite said first end forming a U-shaped hook, wherein said two hooks are configured to attach to said grille but not permanently fixed to said grille and detachable, wherein pulling said free end of said elastic cord tightens said looped end and said hooks, and wherein said free end of said elastic cord fits through one of said two small holes in the center area of said cover and is stowed into the other said small hole in the same said cover; (c) a barrel lock, which is larger than said small holes, is located on an opposite side of said cover than said looped end and along a trunk of said elastic cord for controlling a slack of said trunk projecting outside said cover creating tension and locking said cover to a vent area.
