Abstract: According to the invention, a compressible, resilient baffle member is provided and held captive compressibly against a partition wall in a refrigeration apparatus machinery compartment by a resilient retainer clip. The retainer clip straddles the baffle member surface and has legs which terminate in offset free ends which extend into a specially configured aperture in the partition wall. The baffle member biases the offset ends of the clip legs into contact with the surface of the wall opposite to the baffle mounting surface. When the baffle is rotatably displaced the one clip leg slides into the aperture and the opposite leg rotates about an edge of the aperture. The resilience of the baffle member and clip restore the baffle to the original position.
