Clamp

A clamp for compressing a junction of a first conduit and a second conduit to seal the junction, the clamp comprising:

• a ring sector and a radially projecting channel sector;
• the radially projecting channel sector having first and second straps, each of the first and second straps extending outwardly from the ring sector at an angle defining a pinch point, and defining a proximal gap between the pinch points less than a distal gap between ends of the first and second straps;
• a wedge shaped spacer between the first and second straps, the wedge shaped spacer having a first arm and a second arm extending from a web, wherein the second arm extends further from the web than the first arm;
• first and second compression members adjacent to and opposite the first and second straps from the wedge shaped spacer, each compression member having a tab with a first knuckle and an overlapping ear with a second knuckle, the first and second knuckles at least partially aligned, and each ear having a portion thereof disposed at a pinch point;
• each of the first and second compression members, the first and second straps, and the second arm having an aperture in registry with each other;
• a bolt extending through the apertures and having a head bearing against one of the first and second compression members;
• and
• a nut on the bolt and bearing against the other of the first and second compression members;
• wherein when the nut is tightened on the bolt with the ring sector around a junction of a first outer conduit and a second conduit, the first and second compression members will be drawn toward each other such that the drawing of the first knuckles toward the second knuckles urges the pinch points toward each other thereby drawing the ring sector around the first and second conduits in compression.
