Abstract: A quick-coupling device having a support (18) on which a female member (20) is mounted in a manner to move between a position of retaining a male member (14E) in a position fitted into the female member (20) to a position of releasing the male member (14E) from the female member (20). This device has a lever (24) articulated to the support (18) between a rest position, wherein the lever (24) is separated from the female member (20), to a position of collaboration that allows the female member (20) to be driven toward a position to allow the male member (14E) to be released. The lever (24) includes structure (26) for guiding the male member (14E) in such a way as to encourage guidance of the male member (14E) to mate with the female member (20) when the lever (24) is in the rest position.

Abstract: An electrical switch for a level detection device in a functional fluid container (12) of a motor vehicle brake system, comprises two electrically conductive terminals (32, 34) and a first reed bulb (36), forming a dipole electrically connected to the two conductive terminals (32, 34). The reed bulb (36) is capable of occupying two states, one open and one closed, each state depending on whether the situation is normal or exceptional.

Abstract: A quick-coupling device comprises a support (18) on which the female member (20) is mounted such that it can move between a position of retaining the male member (14E) in a position fitted into the female member (20) and a position of releasing the male member (14E) from the female member (20). This device also comprises a lever (24) articulated to the support (18) between a rest position, separated from the female member (20), and a position of collaboration with the female member (20), allowing this female member (20) to be driven toward its position in which it releases the male member (14E). As a preference, the lever (24) comprises means (26) for guiding the male member (14E), these being positioned on this lever (24) in such a way as to encourage guidance of the male member (14E) to mate it with the female member (20) when the lever (24) is in the rest position.
