Abstract: The subject matter of the present invention is a sealing system configured to form a leak tight electrical connection on a face of an electrical equipment, said sealing system including: a base, comprising a first plate, comprising a through orifice of which the edge is continually comprised in a face of said first plate, a plug comprising a second plate comprising at least one through hole, configured for the passage of at least one electric wire, and a part projecting from said plate suited to being inserted into the orifice, a face of the second plate coming against a face of the first plate, said plug having a flexibility greater than the flexibility of the base, such that the difference in flexibility ensures a constraining of the second plate on the first plate, in such a way as to ensure the sealing of the electrical equipment.
