  • a connector according to claim 1 characterised in that said fixed part of said connector comprises a casing adapted to be fastened sealingly to an aperture provided in the wall of said integral device and opening towards the outside, said fixed connector block comprising a first insulating block carrying the aforesaid fourth series of electrical connecting means, the axes of which are paral lel to the longitudinal axis of said casing, said first insulating block being fastened transversely, securely and sealingly in said casing and forming the bottom of said casing, said movable dead face comprising a second insulating block carrying the said second and third series of separable electrical connecting means in respective electrical connection, said second insulating block fastened sealingly in a sleeve mounted for longitudinal sliding in said casing but secured against rotation in relation to said casing, said sleeve being provided externally with stop means cooperating with corresponding fixed stop means in said casing in order to limit the movement of said sleeve towards the outside of said casing and to provide a seal, and at least one
  • a connector according to claim 2 characterised in that a free peripheral space is provide-d between the side surface of said first insulating block and the inside wall of the casing in order to permit the accommodation of said at least one spring acting on said sleeve carrying said second insulating block.
  • a connector according to claim 2 characterised in that said stop means limiting the movement of said sleeve in relation to the casing have the respective forms of a clack periphery and a valve seat periphery, thus making it possible to provide a seal between the outside and the space contained between said second insulating block and said first insulating block when said stop means are in the cooperating position.
  • a connector according to claim 2 characterised in that said first insulating block is in turn inserted into a socket fastened sealingly to the rear of the casing, the latter, as well as said blocks, sleeve, and socket, having a circular cross-section.
