The present invention relates to an implantable probe comprising at least one conductive wire (11a, 11b, 11c) and an electrical connector (3), the electrical connector (3) being configured to be connected to an implantable medical device of the device type. cardiac, defibrillation or / and neuromodulation stimulation, in which the electrical connection between the conductive wire (11a, 11b, 11c) and the connector (3) is carried out by means of a first welded hypotube (13a, 13b, 13c) to the conductor wire (11a, 11b, 11c) and welded to a second hypotube (15a, 15b, 15c) of the electrical connector (3). The present invention also relates to a method for electrically connecting at least one conductive wire (11a, 11b, 11c) of an implantable probe (1) to an electrical connector (3), the electrical connector (3) being configured to be connected to an implantable medical device of the cardiac stimulation, defibrillation or / and neuromodulation device type, comprising the steps of: a) housing the at least one conducting wire (11a, 11b, 11c) of the probe (1) in a first hypotube (13a, 13b, 13c); b) electrically connecting the at least one conductive wire (11a, 11b, 11c) to the first hypotube (13a, 13b, 13c); c) at least partially housing the first hypotube (13a, 13b, 13c) in a second hypotube (15a, 15b, 15c) corresponding to the electrical connector (3); d) electrically connect the first hypotube (13a, 13b, 13c) with the second hypotube (15a, 15b, 15c). Figure for the abstract: Fig. 2a La présente invention se rapporte à une sonde implantable comprenant au moins un fil conducteur (11a, 11b, 11c) et un connecteur électrique (3), le connecteur électrique (3) étant configuré pour être connecté à un dispositif médical implantable de type dispositif de stimulation cardiaque, de défibrillation ou/et de neuromodulation, dans laquelle la connexion électrique entre le fil conducteur (11a, 11b, 11c) et le connecteur (3) est réalisée au moyen d’un premier hypotube (13a, 13b, 13c) so
