Abstract

A device at exhaust-gas extraction hoses for extracting the exhausts from the exhaust pipe on a vehicle, whereby the exhaust-gas extraction hose (1) is adapted to be retained at the vehicle (4) in an exhaust-gas extracting position (A), whereby the exhaust-gas extraction hose (1) includes a retaining device (8) which can be located on the vehicle (4) spaced apart from the exhaust pipe (3) and whereby an end portion (6) of the exhaust-gas extracting hose (1) includes and/or cooperates with a tightening device (7) which can by tightened by bending and/or stretching the end portion (6) in an exhaust-gas extracting position (A) when the retaining device (8) is attached to the vehicle (4). The tightening device (7) comprises at least one spring (10) which can be stretched in such a way that said spring, when the retaining device (8) is attached to the vehicle (4), affects the end portion (6) of the exhaust-gas extracting hose (1) in axial direction (B) or in substantially axial direction (B) such that the end portion (6), through a support (11) mounted thereon and/or through its end edge (12), is held with pressure against the end edge (13) of the exhaust pipe (3) and/or against vehicle…
