Disclosed is an apparatus for folding and unfolding a shelter frame, e.g., a tent. A plurality of radially arranged connecting bosses is situated on a connecting piece. A pivoting member pivotally attaches to the connecting boss, and a shelter frame rod attaches to the pivoting member. In the folded position, the pivoting members are rotated toward the center of the apparatus. In the unfolded position, the pivoting members are rotated away from the center of the apparatus. The apparatus is rapidly and easily assembled.
