A connection device attached to one structure includes structures having adjacent slots that are alligned to receive and permit placement of an elongated member, and are subsequently relatively movable to retain the elongated member to restrict or occlude the adjacent slot opening restricting removal, and further provides a sheer force between the structures each having the slot to receive the elongated member, to engage and secure the outer surface of a tubular member received into an aperture common through 2 adjacent members, each member aperture having an axis parallel to and offset from the other, wherein rotation of one of the 2 members causes the surface of the offset aperture and the surface of the non-offset aperture to apply a shear force and/or friction to engage and retain the tubular member. Access to the aperture is provided by slot extending from the aperture to the member periphery.
