A joint for connecting two adjacent flooring panels together in a substantially vertical manner includes a rotatable locking member made of plastic, metal or another resilient material. The rotatable locking member is located within a groove or opening of one flooring panel and the second flooring panel has a tongue shaped to mate with the rotatable locking member. Upon installation, the rotatable member rotates and locks around the back of the tongue via a groove above the tongue. The rotatable locking member includes a resilient arm which is bent away from its initial rest position upon installation, so that when the rotatable locking member locks onto the tongue, the resilient arm is bent providing a biasing force which holds the panel securely in position.
