1. An implantable lead comprising:
at least one conductive wire; and
a connector having a first end and a second end, the connector configured to be connected to an implantable medical device, such as a cardiac stimulation, a defibrillation or a neuromodulation device at the first end, and further comprising a strain relief device integrated with the connector, the connector having an axis extending between the first end and the second end, and the strain relief device extending longitudinally along an axis away from the second end of the connector and essentially parallel to the axis of the connector, the strain relief device comprising a through hole at an end of the strain relief device, wherein the through hole comprises a deflecting wall,
wherein the conductive wire is deflected by the deflecting wall of the strain relief device such that the conductive wire is blocked against the deflecting wall when the conductive wire is stressed in tension, and the deflecting wall extends along an axis which is misaligned with the axis of the strain relief device, and
wherein the conductive wire is introduced at least twice through the through hole so that the conductive wire is arranged in a loop around a portion of the strain relief device.
