A reloadable clipping device comprises a 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 connected to one another via a yoke received within a channel of a capsule to move the clip arms 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 reloadable clipping device further comprises an applicator having a distal portion insertable through an opening of a cartridge housing to be coupled to the clip assembly. The applicator includes a catheter and a control member. The catheter extends from a proximal end to a distal end and includes a lumen extending therethrough. The distal end of the catheter is configured to be coupled to a proximal end of the capsule. The control member extends through the lumen of the catheter and includes a plurality of nodes extending along a distal portion thereof, each node having a cross-sectional area larger than a cross-sectional area of a remaining portion of the control member and configured to be coupled to the proximal end of the clip arms, a distal-most one of the nodes severable from a next immediately proximal one of the nodes, when a force exerted thereon exceeds a predetermined threshold value, to release the clip assembly from the applicator.
