Abstract: The invention relates to a massage device having two modules mounted in relative translation to one another by a mechanism allowing their reversible arrangement in at least one first massage configuration and a second message configuration when the modules are brought together or moved apart from one another. Each of the modules has a rear cap with outer geometry arranged to, in the first massage configuration, form a first massage surface with the cap of the other module. Each of the modules has a front extension with outer geometry arranged to, in the second massage configuration, form a second massage surface with the extension of the other module. The extensions are arranged to be able to interlock with one another when the modules are brought together towards the first massage configuration.
