Described is a coupling device for a joining together adjacent dock segments of a dock installation including an elongate pin portion and at least one clamp portion, each positionable on respective dock segments. The pin portion has at least one elongate first clamp surface aligned along its length with a central longitudinal first axis, the pin portion being configured to be received in a corresponding pin-receiving region adjacent the clamp portion. The pin-receiving region is at least partially bordered by at least one second clamp surface which is aligned with a second axis. The clamp portion is configured to be actuated between an open pin-receiving configuration, at least partially opening the pin-receiving region along the second axis, and a pin-engaging configuration with the first clamp surface engaged with the second clamp surface. The second axis is configured to be substantially parallel with the first axis, and with a lateral axis of at least one of the dock segments, for securing the pin portion therewith, so that the pin portion is rotatable relative to the clamp portion about the first axis to accommodate relative movement between the adjacent dock segments.

Gate hinges include an anchor shaft defining a shaft axis that extends between a first end and a second end. A first support arm is arranged at a position closer to the first end than the second end and extends in a direction normal to the shaft axis from the anchor shaft and a second support arm is arranged at the same axial position as the first support arm along the anchor shaft and extends in a direction opposite the first support arm. The anchor shaft includes a first thread and a second, self-tapping thread. The first thread is arranged along the anchor shaft for an axial length between the first and second support arms and the second thread and the second thread extends axially from the first thread to a tip of the anchor shaft at the second end.
