PURPOSE: To set two limbs in stable conditions at such positions to form an acute angle by releasing a lock element provided at free ends of the limbs in a clip to be used for sealing a plastic bag or the like. CONSTITUTION: An outwardly protruded shoulder part 8 is formed at a free end part 15 of a limb 1. A tightening tab is formed at a free end of a limb 2, and a saw teeth-like tongue member 10 for releasing tightening action between the limbs 1, 2 is provided at the uppermost end of it. A shoulder part 13 provided under the tongue member 10 is composed to be engaged with the shoulder part 8 of the limb 1. As a right end of the tongue member 10 is pressed right and down, engagement between the shoulder part 8 and the shoulder part 13 is released, and by elasticity of a hinge part 12 folding plastic, the limb 1 and the limb 2 are automatically opened to positions to form an acute angle. |
