A perineal probe (1) is provided mainly extending along a main axis and comprising at least two electrodes (2) protruding from the axial direction, spaced one another and electrically insulated along the axial direction and one junction element (3) being apt to mechanically connect the electrodes (2) and mainly extending along the main axis, in which at least one of the electrodes (2) comprises a seat for the junction element (3) apt to realize a first interlocking coupling between the junction element (3) and the seat, the junction element (3) comprising an inner cavity mainly extending along the main axis and elastically deformable portions apt to realize the first interlocking coupling, the probe (1) further comprising an inner body (5) apt to be inserted into the inner cavity and being apt to hinder the elastic deformation of the deformable portions of the junction element (3) in such a way as to prevent the release of the first interlocking coupling.
