A connector assembly for a coaxial cable having a substantially rigid electrically conductive jacket, a center conductor and electrical insulation between the jacket and center conductor, which connector includes a body, a mandrel (which may be part of the body) and a clamp nut. The body is adapted for connection to a junction box or other device to which the coaxial cable is connected and contains insulating means for holding the center conductor of the coaxial cable or a pin which is connected to the center conductor. The clamp nut is adapted to be attached to the body and holds the mandrel for maintaining electrical contact with the jacket of the coaxial cable in electrical contact with the body. This invention provides means for securing the clamp nut to the body to prevent the loosening of the clamp nut from the body and to provide a visual indication that the clamp nut has been loosened from the body or that the connector has been reentered. This security feature and visual reentry indication is particularly desired in the CATV industry.

A wraparound closure article comprising a slit tubular body having upstanding rails extending along the slit is formed by a combination of blow-and compression-moulding. The rails are formed by compressing a longitudinal edge portion of a parison between two parts of a closed split-mould to form a flange, and the tubular body is formed integrally with the rails by blowing the remainder of the parison into contact with the closed mould. The flange is then cut to provide the slit of the wraparound closure article and to divide the flange into two discrete rails. The slit extends along the pinch-line that forms as a result of compressing the edge portion of the parison in the closed mould.
