A clipping device , comprising: a capsule including a longitudinal body and a cap mounted over a distal end thereof so that the cap is movable relative to the longitudinal body from a pre-deployed configuration to a deployed configuration in which the cap , is moved proximally relative to the longitudinal body to reduce a length of the capsule , a channel of the cap and a channel of the capsule being substantially aligned with respect to one another; a pair of clip arms , at least proximal portions of which are received within the channels of the cap and the longitudinal body so that the clip arms are movable relative to the capsule between an open configuration of the pre-deployed configuration, in which distal ends of the clip arms are separated from one another, and a closed configuration of the pre-deployed configuration, in which the distal ends of the clip arms are drawn toward one another; wherein the cap is coupled to the longitudinal body via a pin extending from an interior surface thereof and through a slotted opening extending through a wall along a distal portion of the longitudinal body , the pin longitudinally slidable from a distal end of the slotted opening , in the pre-deployed configuration, to a proximal end of the slotted opening , in the deployed configuration; and wherein the distal end of the slotted opening is sized and shaped to correspond to a size and shape of the pin , the distal and proximal ends of the slotted opening connected via a middle portion having a width smaller than the distal end of the slotted opening so that when a predetermined force is exerted on the cap to move the capsule from the pre-deployed to the deployed configuration, one of the pin and the middle portion deform to permit the pin to be slid proximally along the slotted opening . a capsule including a longitudinal body and a cap mounted over a distal end thereof so that the cap is movable relative to the longitudinal body from a pre-deployed configuration to a deployed configuration in which the cap , is moved proximally relative to the longitudinal body to reduce a length of the capsule , a channel of the cap and a channel of the capsule being substantially aligned with respect to one another; a pair of clip arms , at least proximal portions of which are received within the channels of the cap and the longitudinal body so that the clip arms are movable relative to the capsule between an open configuration of the pre-deployed configuration, in which distal ends of the clip arms are separated from one another, and a closed configuration of the pre-deployed configuration, in which the distal ends of the clip arms are drawn toward one another; wherein the cap is coupled to the longitudinal body via a pin extending from an interior surface thereof and through a slotted opening extending through a wall along a distal portion of the longitudinal body , the pin longitudinally slidable from a distal end of the slotted opening , in the pre-deployed configuration, to a proximal end of the slotted opening , in the deployed configuration; and wherein the distal end of the slotted opening is sized and shaped to correspond to a size and shape of the pin , the distal and proximal ends of the slotted opening connected via a middle portion having a width smaller than the distal end of the slotted opening so that when a predetermined force is exerted on the cap to move the capsule from the pre-deployed to the deployed configuration, one of the pin and the middle portion deform to permit the pin to be slid proximally along the slotted opening . <EOS>
