Abstract

A tubular sleeve has a first end inserted between concentric inner and outer layers of a flexible flowline. The tubular sleeve is welded to the inner sleeve. The tubular sleeve has serrated outer surfaces for cutting into the outer layer of the flexible flowline, or alternatively, has saw tooth edges at its one end for cutting into the outer layer of the flexible flowline. The outer end of the tubular sleeve is fixedly attached to the interior of a cup-shaped end piece, either by a snap coupling or by a threaded connection.
