Abstract
A coupling assembly for elongated elements (1, 2) comprises a pin member (5) having an outward-facing pin surface (12) and a box member (6) having an inward-facing box surface (13). The assembly comprises one or more elongated flexible locking member (30). The pin member (5) is provided with one or more first circular and circumferential groove (31), and the box member (6) is provided with one or more corresponding second circular and circumferential groove (32). When the pin-and-box connection is made up, a set of first groove (31) and second groove (32) are aligned and the grooves form a circular and circumferential channel (41) shaped and dimensioned for receiving the elongated flexible locking member (30).
