The invention relates to a device for blocking a flow in a pipeline under pressure, comprising a clamp member for encasing a section of the mantle surface of the pipeline and comprising a pipe socket with a valve, switchable between an open and a closed position, and a hole-making tool for producing a hole in the mantle surface during sealing between the tool and the pipe socket. A blocking means is adapted to be inserted through the produced hole and to expand in the pipeline for the purpose of blocking the flow in the pipeline. The blocking means consists of a body with a member being guided in the pipe socket. Two sliding elements, which are carried by the body, are via the support member adjustable from the outside between an open position, in which it is retracted into the body, and an expanded blocking position, in which it seals against the inner circumference of the pipeline.
