Abstract
A connector comprises at least one plug for mating with a bore of a corresponding socket. A main chamber contains protecting fluid communicating with the bore, the volume of this chamber automatically varying to fill the bore with protecting fluid when the plug is withdrawn from the bore. The connector further comprises a compensation chamber filled with a protecting product, such as grease, under a pressure higher than the pressure prevailing in the main chamber. Upon withdrawal of the plug from the socket, a predetermined amount of protecting product is transferred from this compensation chamber to the assembly formed by the main chamber and the bore of the socket.
