ABSTRACT:
A cable handler link (10) includes a body portion (12) having a first wall and two opposed side arms integral with and extending generally perpendicular to the first wall defining a first channel for receiving one or more service lines. The side arms define free ends, arc capable of being deflected and each defines a first engaging formation in the form of a rebate (60). A closure means (14) includes an end wall (14) from which extend two relatively shorter side arms (16, 17) defining complementary engaging formations including a tenon (62) for interlocking the closure means to the side arms of the body portion (12). The side arms deflect towards each other to disengage the closure means from the body portion (12). The rebate (60) and tenon (62) are preferably slightly inwardly tapered and prevent relative transverse movement of the components, which is also the direction in which the link is towed, in use.
