Abstract: A sealing strip for a vehicle door opening has a generally channel-shaped gripping part supporting a tubular sealing part. Initially, the side walls of the channel of the gripping part are splayed apart so as to enlarge the mouth of the channel. This eases the application of the gripping part to the normal mounting flange surrounding the vehicle door opening. The flange can pass freely between gripping lips on the opposite inside walls of the gripping part. A suitable tool is then employed to press the side walls of the channel towards each other so as to render them substantially parallel, thus pressing the lips into gripping and sealing contact with the flange surfaces, this configuration being therefore resiliently maintained by a metal carrier embedded in the gripping part. One of the sealing lips is particularly advantageous for secondary sealing purposes because it is directed outwardly of the mouth of the channel, unlike the other lips.
