Abstract: A machine for applying a metal wire clip to intersecting first and second tubular elements arranged in vertical and horizontal configuration, comprising a machine housing, a handle extending from the housing and a trigger pivotally arranged for operable movement toward and away from handle, a first mechanism for feeding wire clips, one-at-a-time, into the machine housing for forming the clips into a U-shaped clip element defined by a central concave bight area and a pair of legs extending substantially mutually parallel and outward from the bight area; a second mechanism for moving the clip element out of the machine housing and into contact with the first tubular element, and a third mechanism for deforming the legs upward about the second horizontal tubular element to clasp both first and second tubular elements together.
