Connectors for attaching a composite pipe to a service member are described herein. In one embodiment, a connector can include a service end, a slip nut, a slip, a seal carrier, and an energy conductor. The slip nut can be disposed about the outer surface of the pipe and can be engaged by the service end. The slip can be positioned about the outer surface of the pipe and can be engaged by the service end and the slip nut to compress the slip into gripping contact with the pipe. The seal carrier can be positioned in a bore of the pipe at a location radially opposite the slip to resist deformation of the pipe when the slip is compressed into gripping contact with the pipe. The energy conductor can be embedded within and surrounded by a material of the service end for connection with an energy conductor within the composite pipe.
