US Patent 7313849 Fastener for a lace

A fastener for a lace includes a fastening body and a pull unit. The fastening body includes a base, and at least one clamp assembly having a substantially U-shaped member which have two pivoting ends pivotally connected to the base to define an opening with the base, and a clamp member which is attached slidably to the U-shaped member and which extends across the opening to divide the opening into a first aperture proximate to the base and a second aperture distal from the base. The U-shaped member has a U-bend cooperating with the clamp member to confine the second aperture. The clamp member is slidable along the U-shaped member between a clamping position and a releasing position. The pull unit is connected to the U-shaped member.
