The invention relates to an energy dissipating device suitable to be used as part of a connection device that connects a first car of a multi-car vehicle with a second car of the multi-car vehicle, comprising an energy dissipating member that dissipates energy when it is deformed, whereby the energy dissipating member has a first end and a second end, the first end and the second end being spaced apart from each other in a compression stroke direction, a stopper with a stopping surface, whereby the first end of the energy dissipating member is in contact with the stopping surface, the stopping surface preventing that the first end moves into the compression stroke direction, a deformer that is in contact with the second end of the energy dissipating member and is held apart from the stopper by the energy dissipating member, whereby the deformer can be moved towards the stopper by application of a linear force pointing in the compression stroke direction that is larger than a predetermined threshold value and whereby the deformer deforms the energy dissipating member when moving towards the stopper, a guide that interacts with the deformer to guide the deformer to move in the compression stroke direction, whereby the guide has a three-dimensional guide surface that interacts with a surface of the deformer, whereby the guide surface extends in a direction parallel to the compression stroke direction and that the cross-section of the guide surface in a plane that is normal to the compression stroke direction has the form of an arc or the form of a ring.
