Various embodiments concern a suture sleeve for securing an implantable lead with a suture. The suture sleeve can comprise a tubular body having a proximal end portion, a distal end portion, an exterior surface, and a lumen, the lumen sized to receive the implantable lead. The suture sleeve can further comprise a suture receiving area along the tubular body, the suture receiving area within a channel that extends around a circumference of the tubular body. An exterior surface of the suture receiving area can comprise a tear resistant feature. The tear resistant feature can be configured to resist initiation of a tear in the exterior surface from the suture. The lumen can comprise an inner surface configured to frictionally engage the implantable lead.
