A vertical or block chain connector (10) for linking between two closed chain links (15) comprises a lower element (12) and an upper element (14) configured to engage with the lower element (12) to form the chain connector in an assembled condition. In use the lower element (12) is disposed vertically below the upper element in the assembled connector. The lower element defines a longitudinally extending base portion (20), end walls (22, 24) and a central pillar (26) at the top of which engaging formations are defined to engage with the upper element (14). The height of the walls and the central pillar is preferably higher that the height of the links (15) when the chain is in a horizontal orientation. The upper element (14) is a sliding fit with the lower element (12) and the direction of the sliding connection is in a straight line perpendicular to the longitudinal axis of the connector and in a plane which is parallel to the horizontal axis when the connector is vertically oriented in use. The upper element can be slid onto the lower element when the links (15) are substantially horizontally oriented so that the connector can be removed and replaced with no or minimal decrease of tension in the chain.
