Seals with a flexible central portion are alternated with the contacts and with the latter define a bore to accommodate the pin. A chamberfilled with dielectric liquid is defined within the housing as a rear extension of the bore, the entry of which is closed to external fluid by a sealing member. A free space is left around the flexible portion of each tubular seal, and each of said spaces communicates with the aforementioned chamber, means are provided by which the pressure increases in. the chamber when the pin is inserted. The pressure rise'in the spaces around the seals increases the pressure force of the seals against the pin.
