ABSTRACT:
There is provided a clamping member for attaching one part of a two part coupling device to a conduit, such as a hose, said clamping member comprising a body section having a bore running therethrough and comprising a first end portion, an intermediate portion and a second end portion, said first end portion being adapted to be connected to one part of the two part hose coupling device. The clamping member further includes at least a pair of spaced apart clamping rods each of which is pivotally connected to the body section of the clamping member, each of said clamping rods including a clamp section connected at one end of said rod, and an annular ring disposed about said body section in contact with said clamping rods, so that when a hose is inserted in the second end portion of the body section, the annular ring member can be positioned so as to bear against the connecting rods and force the connecting rods to be pivoted downwardly so that the clamp section thereof will be forced against the hose and thereby hold the hose in said body section.
