A bracket, for attaching a support to a wheelchair frame, includes a coupling with a first body, a second body, and a link. The first body has a first bore with a clamp there around and has one connector for connection to the support or the wheelchair frame. The second body has a section with a second bore and which is received within the first bore and releasably engaged by the clamp. The second body has a second connector for connection to the other one of the support and the wheelchair frame. Releasing the clamp allows the first and second bodies to be separated so that the support can be moved with respect to the wheelchair frame, while the link, captured in the first and second bores, prevents total separation of the bodies. A key and keyway limit assembly of the first and second bodies in only one orientation.
