ABSTRACT:
A clip which is to separably couple an elastic belt conveyor with the leader of a web of photographic material has a slotted arm which is connectable to the leader and a frame which is integral with one end of the arm and has a square window bounded at two of its sides by triangular or square projections. The belt conveyor is caused to buckle so as to reduce its effective width, and one of its marginal portions is inserted in front of one of the projections from one side of the frame prior to insertion of the other marginal portion in front of the other projection. The projections engage one side of the conveyor and the other side of the conveyor is engaged by one side of the frame in front of and behind the window. The clip is flat and its arm is integral with the frame. The width of the window in the frame is somewhat less than the width of the conveyor.
