ABSTRACT:
A fastening device for repeatedly loosenably fastening a lace without detachment, including a panel body and at least one engaging block. Two ends of the panel body are formed with cut sections each having a locating shaft. The locating shaft is formed with a concave. The central portion of the panel body is formed with multiple lace holes through which the lace is passed. The engaging block is formed with a central recess in which the locating shaft is fitted to define a lace access gap. The wall of the recess of the engaging block is formed with stopper projections. A resilient tongue plate is formed on outer edge of the recess. When the engaging block is forcedly outward turned by a lace passing through the gap, the tongue plate and the stopper projections provide resilient restoring pressure due to the change of distance between the centers of the locating shaft and the recess. The restoring pressure acts as a clasping force for clamping and tightening the lace. When the engaging blocks at two ends of the fastening device are pinched, the lace is released from the clasping force, permitting the fastening device to be freely slided along the lace to a desired position without detaching from the lace. Then the lace can be pulled to be again tightened by the fastening device.
