A two-part surgical ligation clip includes a track having two substantially symmetrical arms and a clip for slidably receiving the track, The symmetrical arms are connected together at a proximal end to form an apex and have spaced-apart tips at a distal end with first complementary surface. The track also includes a connector connected to the apex and having a second complementary surface. The clip has an extended slot for slidably engaging the track and distal end tips for receiving the connector. A distal end of the clip has a first contour surface for engaging the first complementary surface on the track and locking it in a closed position and a second contour surface for engaging the second complementary surface on the track and locking it in an open position. A two-part ligation clip applicator, which is also disclosed, comprises a handle assembly having a squeezable trigger and an elongated shaft connected at its proximal end to the handle assembly. The elongated shaft houses a sliding advancer which is actuated by squeezing the trigger to move axially in a forward direction in the shaft. In addition, a module is mountable at a distal end of the elongated shaft and supports a ligation clip. The module has a cartridge housing, latches pivotably mounted within the housing for gripping first part of the ligation clip, and a sliding pusher slidable within the housing by actuation of the advancer to engage the second part of the ligation clip and advance it relative to the first part to close the first part.
