Abstract: A towing arrangement intended for train couplers includes a bar (8), which at a rear end has an axially projecting pin (10), which projects through a through hole (40) in a plate (11), which on both sides is surrounded by shock-absorbing spring members (12), which always aim to hold the pin in a starting position in relation to the plate, and against the action of which the pin together with the bar are axially movable. The plate (11) is included in a mandrel (16) equipped with a cone (19), which mandrel is inserted into a deformation tube (17), more precisely into a wide, front tube section (22), which via a waist (23) transforms into a thinner, rear tube section (21), which is deformable by the mandrel (16). A deformation tube is also described.

Abstract: A clamping arrangement (3) for the fixation of a towing arrangement (2), equipped with a mounting flange (14), in a mounting pocket (6) included in a vehicle underframe (1) and being of the type that includes front and rear pairs of stop lugs (11, 12). The clamping arrangement includes a form-stiff insert (4) as well as a clamping device (5), which is applicable between the insert (4) and the mounting flange (14) of the towing arrangement (2) in order to press apart these and thereby clamp the mounting flange (14) against the front pair of lugs (11). A railway vehicle, e.g. a railroad car, provided with a towing arrangement is also disclosed.
