18. ABSTRACT The present invention relates to a retaining and relea- sing device for an exhaust-gas extraction nozzle, which nozzle (5) is adapted for extracting exhaust gases from upwardly directed exhaust pipes (3) on vehicles, e.g. fire-fighting vehicles, when these vehicles are started and driven in premises for said vehicles, e.g. a fire station. To permit safe retention of the nozzle (5) at the exhaust pipe (3) with sufficient forces without said forces counteracting release of said exhaust pipe (3) from said nozzle (5), the retaining and releasing device includes at least one retaining and releasing arm (29) which is movable between a retaining position (D) wherein it permits retention of the exhaust-gas extrac- tion nozzle (5) at the exhaust pipe (3) and a releasing 19. position wherein it permits release of said exhaust pipe (3) from said nozzle (5), whereby a retaining device (43) is provided to retain the retaining and releasing arm (29) in its retaining position (D) and to release the arm (29) such that said arm can move to its relea- sing position when the exhaust-gas extraction nozzle (5) reaches a certain position in the premises (1).
