A gas-tight connector, especially for the remote handling of radioactive or hazardous products by means of a master-slave manipulator. The connector is composed of a tong-unit connector element, a gas-tight connector element and a remote-manipulator connector element. The gas-tight element is engaged coaxially within the tong-unit element and the remote-manipulator element is engaged coaxially within the gas-tight element and also coupled to an articulated supporting arm. All three elements are traversed from one end to the other by shafts which are capable of translational motion in order to initiate opening and closing of the tong unit. The gas-tight element is provided with a sealing diaphragm which is capable of unfolding throughout each range of translational motion of the gas-tight element shaft while accompanying this latter and ensuring that a high standard of gas-tightness is maintained between the gas-tight element and the remote-manipulator element during all the forward and return movements of the shaft.
