Abstract: A wall-mountable holder (1) for retaining an article such as a bicycle. The holder (1) comprises a support frame (2) having a wall-mounting bracket (6), and a pair of jaws (3, 4) pivotally mounted to the support frame (2) to define an article-receiving region between the jaws (3, 4). The jaws (3, 4) are moveable between an open position and a closed position, and the jaws (3, 4) can releasably lock to the support frame (2) when in the closed position. When a bicycle wheel is urged against proximal ends of the jaws (3, 4), the jaws (3, 4) pivot to the closed position, the jaws (3, 4) lock to the support frame (2) and the jaws (3, 4) retain the wheel. When the wheel is pulled away from the proximal ends, the jaws (3, 4) pivot to the open position and enable the wheel to be removed.
