The female portion includes an inner threaded portion (16d) and an outer threaded portion (16b) which are offset radially with respect to a longitudinal axis of the first tubular component by a first shoulder (16c). The second tubular component (14) includes a male portion (18) defined on an exterior surface of the second tubular component (14). The male portion is to be inserted into the female portion, and includes an inner threaded (18b) portion and an outer threaded portion (18d) which are offset radially with respect to a longitudinal axis of the second tubular component by a second shoulder (18c).
