<p>The invention concerns a sealing device for sealing at least one cylindrical pipe (12) having a predefined perimeter, in particular a pipe of a motor vehicle, comprising: -at least two sealing elements (16) disposed in superimposed layers, a sealing element (16) forming an upper layer having a higher level of rigidity than a sealing element forming a lower layer and, -at least one port intended to receive said pipe (12), said port passing through the layers perpendicularly and being formed from a opening (26) passing through each sealing element (16), the axes of said openings coinciding, characterised in that, for each port, the opening (26) passing through the sealing element (16) forming the upper layer has an elliptical shape of which the perimeter is smaller than or equal to the perimeter of the pipe (12) received in said port, each elliptically shaped opening (26) having the same orientation.</p> |
