ABSTRACT:
A device for closing a sliding door comprises a pair of slidable telescoped tubes. The device is secured at its outer ends to the sliding door and to a supporting door frame. A compression spring is located within the tubes urging the sliding door to return by itself from its open to its closed position. A string extends between the end portions of the tubes to prevent the tubes from being separated and a clamping means is adapted for locking the sliding door in any desired open position.
