Clamping device attachable to the side of a crutch for carrying thin, flat, non-rigid articles or a 12 oz. beverage can, having a preload to firmly hold articles in place. The device is attachable to a variety of crutch frame cross-sections and widths by a single bracket at the top of the device connected to the crutch handgrip bolt by a wingnut. At least one adjustable strap prevents the lower end of the device from pivoting away from and banging against the crutch frame. One embodiment comprises an L-shaped member and a spring-biased hinged member connected to and preloaded against the L-shaped member for clamping articles therebetween. In another embodiment a molded plastic J-shaped member has a thinned portion at the base of the short leg of the J to provide resiliency. A spacer between the outer end of the resilient short leg and the clamp surface of the rigid long leg provides a preload force between them. Alternatively, an adjustably slidable connection between overlapping parts of the J-shaped clamp enables preloading without the spacer.
