A control barrier is provided having a barrier wall with one or two support assemblies attached thereto. The barrier wall has a front face with a display recess, wind ports, and tenons and mortises formed thereon. The barrier wall also has a set of projecting arms having either pins or ports to allow a series of control barriers to be connected together. The support assemblies are positionable between a support position and a standing position. Preferably, the support assemblies include a leg and a foot. The leg is extendable and/or rotatable to allow the foot to be positioned between a support position and a standing position.

A clamp for fixing a seat post of a cycle in a seat tube having a longitudinal slit that enables it to have a first condition with first interior and exterior diameters and a second condition with second interior and exterior diameters, the clamp comprising: a body portion that has a generally circular aperture of a predefined shape, has an inner cylindrical surface with a diameter at least equal to the seat tube's first exterior diameter and free ends which define a slit tangential to the diameter of the cylindrical surface; one free end defines a through passage and the other free end defines a receptor opposite the passage; and a fastener located in the passage and mated with the receptor; whereby movement of the fastener into the receptor reduces the diameter of the cylindrical surface while preserving the generally circular aperture of predefined shape, draws the free ends together and reduces the tangential slit sufficiently to bring the cylindrical surface into contact with seat tube and the reduces the interior diameter of the seat tube to the second interior diameter and fixing contact with seat post. 6. A clamp for fixing a seat post of a cycle in a seat tube having a longitudinal slit that enables it to have a first condition with first interior and exterior diameters and a second condition with second interior and exterior diameters, the clamp comprising: one free end defines a through passage and the other free end defines a receptor opposite the passage; and a fastener located in the passage and mated with the receptor; whereby movement of the fastener into the receptor reduces the diameter of the cylindrical surface in a generally uniform manner, draws the free ends together and reduces the tangential slit sufficiently to bring the cylindrical surface into contact with seat tube and the reduces the interior diameter of the seat tube to the second interior diameter while maintaining its shape and fixing contact with seat post. 7. A clamp for fixing a seat post to the seat tube of a bicycle, said seat tube having an axially-extending compression slit in the wall of the seat tube, comprising: a) a pair of elastically deformable branches defining a through hole having a predetermined shape, a diameter and a cylindrical inner surface, said branches integrally formed and conjoined at one end and having an enlarged-thickness at the other free end; b) opposed face surfaces on the free ends of said branches, said face surfaces having a stepped configuration and forming a clamp slit extending to the inner surface of the through hole at an inclined angle relative to all radii extending to said through hole; c) coaxial bores extending through the free ends of said branches, each bore extending at an inclined angle relative to said clamp slit; and, d) a tightening screw extending through said bores. 8. A clamp for fixing a seat post (14) to a bicycle seat tube having a vertical slit (12), the clamp comprising: a pair of integrally formed and conjoined branches (24a, 24b) that define an cylindrical inner surface (20), each branch having a free end with a through hole of substantially equal size
