ABSTRACT:
A clamping mechanism for connecting members in end-to-end relation having a rotatable, actuating ring to radially move loading devices into engagement with one of the members. The translation of rotational movement to radial movement is accomplished by cam mechanisms. The loading devices may be toggle links of a toggle assembly which are supported by one of the members to be connected. Rotation of the actuating ring advances the locking device into engagement which in turn connects and preloads the members.
