The friction clamp includes a cylindrical body of elongate form between ends and with a slot into which a tubular item is snapped. Lateral connectors such as a receiver with a cylindrical recess therein receive an end of a tubular member, such as a member similar to that which snaps into the slot. As an alternative to the receiver, a tab is provided extending from the clamp laterally. The tab includes a hole through which hardware is placed, and an item having a similar tab is placed adjacent to the tab extending from the clamp and the hardware tightened for fixation at a desired rotational orientation. As another alternative to the receiver, a small friction clamp connector is provided on an exterior of the friction clamp. A small rod (or other item) snaps into the small clamp. The small clamp and rod can be provided separate from the friction clamp.
