1. 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 longitudinal body being substantially aligned with respect to one another; and
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 aims are movable relative to the capsule between an open configuration, in which distal ends of the clip amus are separated from one another, and a closed configuration, in which the distal ends of the clip arms are drawn toward one another, wherein at least one of the clip arms includes an engaging structure engaging a portion of the cap so that, when a predetermined proximal force is exerted thereon, the capsule is moved from the pre-deployed configuration to the deployed configuration.
