Abstract: An apparatus for constricting or closing a conduit comprises a pair of generally parallel clamp frames opening in the same direction and disposed at a separation such as to accommodate the conduit between them, the clamp frames being formed in one side of their opening with a recess in which fits a stationary clamp member and being secured on their other side to a fluid operated ram that actuates a movable clamp member towards the stationary clamp member. After operation of the ram the two clamp members are fastened together, eg by bolts, and then the ram is retracted. The clamp members can then be removed from the clamp frames.
