A system for treating tissue, comprising: an applicator including a catheter and a control member extending therethrough, the catheter extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough, the control member longitudinally movable relative to the catheter and including an abutment structure proximate a distal end thereof; and a clip assembly releasably coupleable to a distal end of the applicator , the clip assembly including a pair of clip arms , each of the clip arms extending from a proximal end to a distal end , the proximal end of each of the clip arms slidably received within a channel of a capsule and configured to be releasably coupled to the distal end of the control member so that the clip arms are movable relative to the capsule between a tissue receiving configuration, in which distal ends of the clip arms are separated from one another, and a tissue clipping configuration, in which distal ends of the clip arms are moved toward one another, the capsule including proximal tabs movable between a biased non-engaging configuration, in which the proximal tabs extend into the channel , and an engaging configuration, in which the proximal tabs extend laterally outward relative to a longitudinal axis of the capsule to engage an engaging portion of the catheter , wherein the abutment structure maintains an engagement with the proximal tabs , holding the proximal tabs in the engaging configuration, while the abutment structure is received within the capsule characterised in that the clip arms include a locking tab extending laterally outward therefrom and being configured to engage a portion of the capsule when the clip arms have been drawn into the capsule by a predetermined distance, the locking tab being configured to lock the clip arms in the tissue clipping configuration. an applicator including a catheter and a control member extending therethrough, the catheter extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough, the control member longitudinally movable relative to the catheter and including an abutment structure proximate a distal end thereof; and a clip assembly releasably coupleable to a distal end of the applicator , the clip assembly including a pair of clip arms , each of the clip arms extending from a proximal end to a distal end , the proximal end of each of the clip arms slidably received within a channel of a capsule and configured to be releasably coupled to the distal end of the control member so that the clip arms are movable relative to the capsule between a tissue receiving configuration, in which distal ends of the clip arms are separated from one another, and a tissue clipping configuration, in which distal ends of the clip arms are moved toward one another, the capsule including proximal tabs movable between a biased non-engaging configuration, in which the proximal tabs extend into the channel , and an engaging configuration, in which the proximal tabs extend laterally outward relative to a longitudinal axis of the capsule to engage an engaging portion of the catheter , wherein the abutment structure maintains an engagement with the proximal tabs , holding the proximal tabs in the engaging configuration, while the abutment structure is received within the capsule characterised in that the clip arms include a locking tab extending laterally outward therefrom and being configured to engage a portion of the capsule when the clip arms have been drawn into the capsule by a predetermined distance, the locking tab being configured to lock the clip arms in the tissue clipping configuration. <EOS>
