Claim:
A lock comprising a housing; a handle that is pivotally connected to the housing for movement between a closed position wherein the handle positions a pointed tip of a fastener carried by the handle to engage with a surface along which the housing is movable, and an open position that positions the pointed tip out of engagement with the surface; a torsion spring interposed between the handle and the housing biasing the handle toward the open position; a trigger pivotally connected to the handle for movement between an unlatched position wherein the trigger disengages a formation of the housing, and a latched position wherein the trigger engages the formation to retain the handle in the closed position; a compression spring interposed between the trigger and the handle for biasing the trigger toward the latched position; and a stiff yet bendable leaf spring connected to the handle and biasing the pointed tip of the fastener into engagement with the surface when the handle is in the closed position.
