Abstract
The opposite ends of at least one pair of tubular members, for instance steel tubes, are closed by inserts which have radial portions overlying end faces about the open ends of the tubular members. The tubular members are then axially aligned with each other while maintaining the radial portions of the inserts spaced from each other, whereafter the tubular members and the spacing therebetween are covered with a jacket of plastic material. Subsequently thereto, the jacket is severed intermediate the annular portions of the inserts to thereby obtain two discrete tubular elements.
