A retaining device for securing insulation to sheet metal has a flange, an articulated structure and a push plate having an aperture therethrough such that when the retainer, except for the flange, is inserted in a hole in the insulation layer it allows a push plate to be pushed towards the flange, causing a pair of locking fingers to pivot and press up against the underside of the insulation in a locked position. The retaining device is then frictionally fitted over a stud member on the sheet metal to which the insulation layer is to be secured.
