In order to fill the cryogenic engines of a launcher with propellents up to the time of launcher lift-off, an apparatus is proposed which has a tube section (20) connecting pipes on the ground and on board the launcher (12). A weakened zone (22) of said tube section is automatically broken during lift-off by a mechanism (24,38) applying a tensile stress to the section. This mechanism comprises several assemblies of links (26,28) bearing on the tube section on either side of the weakened zone and a bearing surface (38a,38b) formed in a sleeve (38) fixed with respect to the ground and with which is in contact a protuberance (26a) formed on one of the links of each assembly (26,28).
