Abstract: A bag closure clip is provided which consists of a pair of arms, each having a handle at a first end and a jaw at a second end and a hinge mechanism for permitting pivoting the arms to move from an open position in which the jaws are separated to a closed position so that the jaws are together. Another mechanism is provided for biasing the arms to the closed position, so that the jaws are normally together, to make an airtight seal on a plastic bag. When the handles are manually squeezed together the arms will move into an opened position to separate the jaws and release the airtight seal on the plastic bag.

Abstract: A hook and loop-type fastener system is provided with a shield disposed between the mated, juxtaposed hooked and looped surfaces of the fastener to preclude premature and inadvertent engagement. Once the two components of the fasteners have been properly positioned relative to one another, the shield may be removed, thereby facilitating engagement and bonding of the surfaces to one another.

Abstract: A clasping device for fastening a large cargo which includes a lever pivotally connected to a body through a pair of links. A belt is tightened by pivoting the lever relative to the body in a fastening direction in such a way that the pivotal connection between the links and the lever move in the direction of the interior of the body when the lever is pivoted in a fastening direction, thereby to render the device compact in the fastening position.
