An articulated arm for supportably attaching a movable first body to a second body comprises a connector bar which fits inside a substantially hollow sheath, each of the connector bar and sheaths being pivotally attached to a first intermediate member at a first end thereof and to a second intermediate member at a second end thereof. Fasteners are provided to temporarily and disengagably fix the position of the connector bar with respect to the sheath. Hardware is described for attaching the first intermediate member to a movable first body and for attaching the second intermediate member to a second body which is substantially stationary with respect to the first body.
