A closure for sealing the mouth of a bag including a bowed strap and a clamping bar struck from the interior thereof and hinged at one end to the strap. Striking the clamping bar from the interior of the strap leaves an elongated slot in the strap defined by a plurality of contiguous edges. A hook is provided on the other end of the clamping bar which can be snapped over an edge of the slot in the strap with one hand to lock the strap and bar together. Prior to locking them together, the mouth of the bag to be sealed is inserted between the strap and clamping bar.
