The invention relates to a device for preventing the drift of a seal in a vibrating environment, said seal being held between two components braced against each other with the aid of tensioning means (18). The inventive device is designed particularly to prevent the drift of a seal (4) placed between a multipoint connector (14) and a housing half-shell (1) of a vehicle clutch actuator. Said device comprises stop faces (34, 36) for the joint (4), which act in a plane substantially perpendicular to the direction of constraint, said stop faces being at least partially formed on the tensioning means (18). |
