A connector () for releasable connection between an anchorage in the form of a female part () arranged on a floating means and a male part () formed at the end of a retrievable umbilical () provided with a bend stiffener () is disclosed. The male part () comprises a mandrel body () having a pulling head () for connection to a pulling means at one end and the umbilical () at the other end. The male part () comprises a sleeve formed body () that is fixed to the mandrel body () by shearable elements (). The bend stiffener () is fixed directly to the sleeve formed body () and is designed for abutment against and parking together with the bend stiffener () within the female part () while the remaining part of the male part () including the umbilical () is designed to be pulled further up through the female part () for fluid communication and connection on a floating means or a vessel.

A composite pipe having at least one metal end piece () with a free end and a non-metal tubular component (). The tubular component () is coupled to the at least one end piece () opposite of the free end of the end piece (), by means of at least one peripherally extending, axially acting groove () that the non-metallic tubular component () engages. The non-metallic tubular component () generally comprises axial fibers () extending down into the at least one groove (). The groove () has a bottom () and a flank (), which flank is located furthest away from the free end of the end piece (). Between the flank () and the axial fibers () there is provided an intermediate layer (). Also described is a method of manufacturing such a composite pipe.
