ABSTRACT:
A tensioning assembly for applying tension to a band-type clamp includes a T-bolt having a shank portion and a T-head portion. The T-bolt is adjustably mounted to a first end of the band clamp and a keeper constructed and arranged to receive the T-head portion of the T-bolt is affixed to a second end of the band clamp. A nut threadably engages the shank portion of the T-bolt and rotation of the nut on the T-bolt draws the head to the T-bolt towards the first end of the band clamp thereby drawing with it the second end of the band clamp. An anti-rotation device is associated with the nut operably engageable with the nut to prevent its rotation. The anti-rotation device cooperates with a force-applying tool, such as a wrench, so that when the tool is placed on the nut, the anti-rotation device disengages from the nut. Preferably the tensioning assembly also includes an indicator remote from the T-bolt and operably associated with it to indicate the achievement by the T-bolt of a predetermined tension.
