1. An implantable lead extension for receiving an implantable medical lead, comprising:

  • an elongated insulative body having a proximal end and a distal end;

    a plurality of electrical connectors on the proximal end;

    a plurality of filars present within the elongated body and being electrically connected to corresponding electrical connectors;

    an extension connector assembly permanently attached to the distal end of the elongated body, the extension connector assembly comprising;

    a body housing a first bore; and

    a spring loaded retention structure within the first bore, the spring loaded retention structure comprising a contact arm, a spring, and a lock arm, wherein the contact arm extends laterally across the first bore and is connected to a hinge point of the extension connector assembly such that movement of the contact arm releases the spring from a compressed state, the lock arm being mechanically coupled to the spring such that when the spring is released from the compressed state, the lock arm moves laterally into the first bore.
