The device comprises two rigid elements 1a, 1b, 2 and an elastomer mass 10 interposed therebetween so as to be deformed when the elements move relative to each other in a longitudinal direction. The device includes a closed space with a restriction element 16 defining two chambers 23, 24 whose volumes vary inversely upon movement of the chamber walls, the two chambers being interconnected by one or more passages, the empty space being filled with a viscous fluid material so as to produce a damping effect in the passages.
