1. A reloadable clipping device, comprising:
a first clip assembly including a pair of first clip arms, each of the first clip arms extending from a proximal end to a distal end, the proximal end of each of the first clip arms connected to one another via a first yoke slidably received within a channel of a first capsule to move the first clip arms between a tissue receiving configuration, in which distal ends of the first clip arms are separated from one another, and a tissue clipping configuration, in which the distal ends of the first clip arms are moved toward one another;
a first cartridge including a first groove therein, the first groove sized and shaped for housing the first clip assembly, the first cartridge including a proximal opening open to an exterior of the first cartridge in communication with the first groove;
a second clip assembly including a pair of second clip arms, each of the second clip arms extending from a proximal end to a distal end, the proximal end of each of the second clip arms connected to one another via a second yoke slidably received within a channel of a second capsule to move the second clip arms between a tissue receiving configuration, in which distal ends of the second clip arms are separated from one another, and a tissue clipping configuration, in which distal ends of the second clip arms are moved toward one another;
a second cartridge including a second groove therein, the second groove sized and shaped for housing the second clip assembly, the second cartridge including a proximal opening open to an exterior of the second cartridge in communication with the second groove; and
an applicator having a distal portion insertable through the opening of the first cartridge to be releasably coupled to the first clip assembly, the applicator including a control member having an enlarged distal end sized and shaped to be releasably received within a first socket of the first yoke and a locking sleeve coupleable to a proximal end of the first capsule via a deflectable tab extending from a free distal end to a proximal end connected to the locking sleeve so that the deflectable tab is deflectable away from a longitudinal axis of the locking sleeve, the deflectable tab including a distal bend extending into a channel of the locking sleeve to engage a first window extending laterally through the first capsule and a proximal bend proximal of the distal bend, the proximal bend extending into the channel of the locking sleeve so that when the proximal bend engages a portion of the control member, the deflectable tab is deflected away from the longitudinal axis of the locking sleeve to disengage the applicator from the first clip assembly, the applicator being configured so that, after the applicator has been disengaged from the first clip assembly, the distal portion of the applicator is insertable through the opening of the second cartridge to be releasably coupled to the second clip assembly so that the enlarged distal end is releasably received within a second socket of the second yoke with the locking sleeve coupled to a proximal end of the second capsule with the deflectable tab extending laterally through the first window.
