Stops made of a synthetic plastics material in two parts welded together at least at individual locations with a fishing line made of "Nylon". The two parts surround with their inner surfaces a hollow space and form an inner wall with elevations. On welding by means of an ultrasonic field at least edges of the elevations melt together with the fishing line and form a non-detachable connection. By means of radial grooves on the outer side the rigid stop achieves a certain pliability so that a certain transfer from line to stop does not cause any break in the line. Such stops are suitable in ocean fishing for limiting the length of displacement of the swivels.
