This light-duty buckle can be attached to straps or belts for a unique and secure fastener for homemade bags, purses, or even belts. The latch mechanism releases "airplane-style" rather than by squeezing or push-button, by gently lifting the flexible latch and pulling the two pieces apart. (See airplane instructions dance video: http://youtu.be/DtyfiPIHsIg?t=52s) Not for personal restraint!
