Patent ID: 7273110

Claim:
A sealing device for shutting down a pipe, comprising an expandable cylindrical sleeve, which is designed with a conical interior, and a rod extending through the cylindrical sleeve, where the rod is provided with a conical portion with an outside adapted to the sleeve's conical inside and with a smallest diameter smaller than or equal to the sleeve's smallest inner diameter in its non-expanded form and a largest diameter equal to or larger than the sleeve's largest inner diameter in its expanded form, where, when inserting the sealing device, the rod is passed in the cylindrical sleeve's longitudinal direction, thus causing the rod's conical portion to come into contact with and be pressed against the cylindrical sleeve's inner surface, with the result that the cylindrical sleeve is expanded and comes into contact with the pipe wall, characterised in that the cylindrical sleeve is provided with radially through-going slots extending in the sleeve's longitudinal direction from each of the cylindrical sleeve's end surfaces, with slots from opposite end surfaces being arranged between one another.
