A clamp comprises a pair of generally semicircular tangs 1, 2 hinged together at one end and connectable together at the other end by means of a screw 5 and nut 4. The tangs have an inwards facing tapered groove 7 for drawing two flanged tubes T into sealing engagement, the screw having a cross-head 6 for engaging in a clevis in one of the tangs, and the clevis having a cross piece 14 distal of the tang for stabilising the clevis and limiting angular displacement of the screw. Preferably the tangs have complementary conical formations 21, 24 for restraining the clevis from spreading as the nut is tightened. |
