A coupling (1, 50, 100) for joining adjacent frame members (2, 3) of a fish breeding enclosure (5) comprises a first mounting means (10, 52, 105, 106) for mounting to one frame member (2), a second mounting means (11, 53, 105, 106) for mounting to another frame member (3) and a flexible body (12, 51, 101) of elastomeric material between the first and second mounting means (10, 11, 52, 53, 105, 106). The coupling (1, 50, 100) constrains relative rotational and translational movement between the frame members (2, 3) in use to a predetermined level which is determined by the material of the flexible body (12, 51, 101) and/or by mechanical limit stops (62, 63). A non flexible connection such as a rod (35) having flanges (36, 37) or a chain (90, 110) provides a mechanical connection between the mounting means (10, 11, 52, 53, 105, 106) in the event of failure of the flexible body (12, 51 , 101). |
