Tennis racket or the like equipped with at least one vibration damping device (9, 10) with viscoelastic material (11) and a constraint plate (12). At least one of these damping devices has a complex cross-section, for example in the shape of a U, so that it partially envelopes, according to different planes or orientations, the zone (6, 7) of the structure to which it is attached. <IMAGE>
