Modular form tube and clamp system

A retention system for retaining a first modular form member in a given orientation with respect to a second modular form member, the first modular form member being formed with a first indentation, the second modular form member being formed with a second indentation, the retention system comprising:

• a first clamping device;
• a second clamping device;
• and
• an elongated tie;
• the first clamping device including a first elongated bar having at least a first protrusion, at least a first clamp, and at least a first tie clip, the at least first protrusion being structured to be engageable with the first indentation, the at least first clamp having a jaw, the jaw of the at least first clamp being structured to removably engage the first protrusion with the first indentation, the at least first tie clip being mounted on the first bar and being formed with an opening that is configured to removably receive at least a portion of the tie therein;
• and
• the second clamping device including a second elongated bar having at least a second protrusion, at least a second clamp, and at least a second tie clip, the at least second protrusion being structured to be engageable with the second indentation, the at least second clamp having a jaw, the jaw of the at least second clamp being structured to removably engage the second protrusion with the second indentation, the at least second tie clip being mounted on the second bar and being formed with an opening that is configured to removably receive at least a portion of the tie therein.
