Abstract: A device for placing spring metal clips in locking engagement with the ends of spacing members. One embodiment of the device comprises a center member and two right angle members disposed adjacent the respective ends of the center member and in a manner that places one leg or extension of the right angle members in a generally perpendicular relationship to the longitudinal axis of the center member. Mechanical linking means connect the two right angle members to the center member in a manner that permits relative longitudinal and parallel movement between them. The linking means includes two pivotal handles spaced apart along the length of the center member for effecting relative longitudinal movement of the center and right angle members. A third member is disposed at the end of the leg or extension of each right angle member that is perpendicular to the center member, and configured to engage the base of a clip.
