ABSTRACT:
A connector assembly for connecting together fluid carrying lines comprises two hubs having the bores of the fluid carrying lines extending therethrough. Openings are provided in the hubs and a clamp is provided in the openings. The clamp is connected to one of the hubs and comprises a clamp body, an operating member and clamping members movable radially outwardly to clamp the juxtaposed hubs together, movement of the clamping members being caused by sliding of the operating member in the clamp body, the inclined external surfaces of the operating member co-operating with the similarly inclined inner ends of the clamping members. The interior of the operating member is hollow and defines a cylindrical internal cavity. A piston is provided in the cavity to form a piston and cylinder assembly for moving the operating member. A releasable lock prevents inadvertent release of the clamping members.
