A device for joining two fluid flow lines includes a pair of connection members threadly engaged to enable a pair of internal abutment surfaces to be moved together when a connection is to be made. A tubular member constituting the terminal end of one of the two fluid flow lines to be placed in flow communication is inserted into the connection device and a clamping member arranged between the abutment surfaces is caused to produce a clamping effect on the tubular member as the two connection members are moved toward each other by threaded engagement therebetween. The clamping member includes a clamping element which will extend obliquely to the axis of the tubular member when in an uncompressed state, with compression thereof by the abutment surfaces causing the clamping element to move toward an orientation perpendicular with the axis of the tubular member whereby a clamping effect is established.
