Abstract
Two adjacent riser pipes having substantially a common axis are connected by the riser connector of this invention in the manner described below. A connector box, adapted to be attached to the end of one of the pipes, has an abutment surface and adjacent to it a channel transverse to the common axis of the pipes. A locking dog fits slidably in the channel, and has a tapered surface facing the abutment surface of the box and at an angle less than 45.degree. to the direction of the channel. A connector pin, adapted to be attached to the end of the other pipe, has a flange. When the flange is in contact with the abutment surface of the box and when the locking dog is pushed towards the flange by a force applying means, the flange of the pin is held between the tapered surface of the dog and the abutment surface of the box, and the connections between the box, pin, and dog are preloaded by forces greater in magnitude than the force applied by the force applying means.
