ABSTRACT:
A clamping device for securing a pole within a U-shaped yoke includes a clamp member pivotally supported on the yoke to open the latter so as to introduce therein an upright pole or to close the yoke to clamp the pole therewithin. The clamp member is provided with a pivotable locking member which has a hook insertable into a slot formed in a side wall of the yoke. A bolt threadingly passes through a hole in the clamp member and is terminated with a bearing plate which abuts the pole to clamp it within the yoke. The yoke is pivotally connected to an X-shaped brace which is fastened to a support surface to support the pole relative to this surface.
