Abstract: A locking device having two sets of pairs of aligned clamping teeth, each set holding one lace end of an elastic lace. Each pair of aligned clamping teeth has a lace insertion portion for snapping an elastic lace laterally through it into a lace holding portion. Last pairs of aligned clamping teeth are dimensioned to hold the elastic lace tighter than the remaining pairs. A pair of cleats may be used to clasp a shoe lace as it comes out of a shoe eyelet so that any further tensioning of the lace will not affect the tightness of the shoe. A shoe hook may also be placed on the back of the locking device.
