The invention relates to a fluid duct (10), particularly an inlet air duct for a combustion engine in a vehicle, having a shell (12) enclosing an inner volume (30) and comprising at least one upper surface (14) and at least one side wall (16, 17), which upper surface (14) represents an upper surface (14) of the fluid duct (10) in its mounted state in an intended position. The side wall (16, 17) is configured to be selectively collapsible upon action of a force (34) applied to the upper surface (14) so that in a collapsed state of the shell (12) the upper surface (14) and the at least one collapsible side wall (16, 17) collapse below a predefined level thus reducing a height (28) of the shell (12).


The present invention relates to a sensor (20) of a filling-level meter of a liquid tank, in particular for an operating liquid, in particular of a motor vehicle, a filling-level meter and tank. The sensor (20) having at least one pair of electric lines (38) for an electric circuit with at least one electric contact (36) each. The electric contacts (36) of at least one pair of electric lines (38) are arranged such that they are contactless at least in one noncontact state of the filling-level meter. The electric contacts (36) can be connected in at least one contact state by use of at least one mechanically operated electric connecting element of the filling-level meter. The electric connecting element does not necessary has to be part of the sensor (20). The at least one electric connecting element can be mechanically connected to a float assembly. The at least one electric connecting element in particular with the float assembly can be moved relative to the at least one pair of electric contacts (36) between the at least one noncontact state and the at least one contact state. The sensor (20) comprises at least one electric bypass resistance (42), which electrically connects the at least one pair of electric lines (38).


The invention relates to a coupling arrangement (10) having a first coupling body (20), a second coupling body (40) and a coupling bracket (30). One of the coupling bodies (40) is insertable with a body portion (42) into a body portion (22) of the other of the coupling bodies (20) with its front end (48) through a front end (24) of the receiving coupling body (20). The coupling bodies (20, 40) provide corresponding catching means (60, 80) for establishing a connection between the coupling bodies (20, 40), the coupling bodies (20, 40) providing a mutual first geometrical position (100) for introducing the insertable coupling body (40) into the receiving coupling body (20). The coupling bodies (20, 40) provide a mutual second geometrical position (102) for locking the catching means (60, 80) in order to establish the connection between the coupling bodies (20, 40). The coupling bracket (30) is configured to cover at least a part of one of the coupling bodies (40) inserted into the other of the coupling bodies (20). At least the receiving one of the coupling bodies (20) provides catching means (64) for establishing a connection to the coupling bracket (30). The coupling bracket (30) provides corresponding catching means (72) for establishing a connection between the coupling bracket (30) and at least the receiving one of the coupling bodies (20).
