A system for treating tissue, comprising: a clip assembly including a pair of clip arms and a capsule (108, 208), each of the clip arms extending from a proximal end to a distal end, proximal ends of the clip arms slidably received within a channel of the capsule to be moved 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; a catheter assembly including a control member extending therethrough, the control member including a distal end configured to be connected to the clip arms to move the clip assembly between the tissue receiving configuration and the tissue clipping configuration; and a coupler (106, 206) releasably coupled to a proximal end of the clip assembly and configured to be coupled to the distal end of the catheter assembly, the coupler configured to fracture to disengage the capsule and deploy the clip assembly, wherein the catheter assembly includes a bushing at the distal end thereof, the bushing configured to be coupled to the proximal end of the coupler, and wherein a proximal portion of the coupler includes a plurality of fingers mountable over a distal portion of the bushing to couple the coupler to the catheter assembly, characterised in that the coupler includes two sets of V-notches (158, 258) diametrically opposed about a circumference of a distal portion of the coupler, each set of V-notches including a proximal V-notch (166, 266) extending from a proximal end of a wall (164, 264) of the coupler and a distal V-notch (168, 268) extending from a distal end of the wall of the coupler, the sets of V-notches configured to fracture when a proximal force exerted thereon exceeds a threshold value. a clip assembly including a pair of clip arms and a capsule (108, 208), each of the clip arms extending from a proximal end to a distal end, proximal ends of the clip arms slidably received within a channel of the capsule to be moved 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; a catheter assembly including a control member extending therethrough, the control member including a distal end configured to be connected to the clip arms to move the clip assembly between the tissue receiving configuration and the tissue clipping configuration; and a coupler (106, 206) releasably coupled to a proximal end of the clip assembly and configured to be coupled to the distal end of the catheter assembly, the coupler configured to fracture to disengage the capsule and deploy the clip assembly, wherein the catheter assembly includes a bushing at the distal end thereof, the bushing configured to be coupled to the proximal end of the coupler, and wherein a proximal portion of the coupler includes a plurality of fingers mountable over a distal portion of the bushing to couple the coupler to the catheter assembly, characterised in that the coupler includes two sets of V-notches (158, 258) diametrically opposed about a circumference of a distal portion of the coupler, each set of V-notches including a proximal V-notch (166, 266) extending from a proximal end of a wall (164, 264) of the coupler and a distal V-notch (168, 268) extending from a distal end of the wall of the coupler, the sets of V-notches configured to fracture when a proximal force exerted thereon exceeds a threshold value.
