Abstract: Connection module for fuelling a space launch vehicle with cryogenic propellant. The module has a ground part placed on the launch pad mast side of the launch vehicle; a flight part fixed to the launch vehicle; a link fixed to the parts to unite them. The module exhibits a passage crossing the ground part, the flight part and the link. The passage allows communication between a line of the launch pad, such as an umbilical structure of the launch vehicle, and a line supplying a tank or a pneumatic circuit of the launch vehicle. Twisting means, such as a lever or an arm, are linked to a disconnection cable. During lift-off, the twisting means apply a torque to the link which causes the breakage of a link groove, allowing the link to split into two axial portions.
