Abstract
A sealing device comprising a hollow body member having a plurality of spaced apart external deformable flanges and provided with a sealant on its external surface, preferably between the flanges. The device may be used to seal a supply line within a duct by pushing it within the duct so that the flanges are deformed, the sealant preferably being provided in a generous amount so that it fills the remaining gaps between the flanges after such deformation. The hollow body member may then be sealed to the supply line using, for example, a heat-shrinkable sleeve. The device may also be used to couple and repair hollow substrates such as gas and water pipes.
