A vertical or block chain connector (10) for linking between two closed chain links comprising a lower element (14) and an upper element (16) configured to engage with the lower element to form the chain connector. In in use the lower element is disposed vertically below the upper element in the assembled connector. The top of the upper element is wider (preferably at least about 10-20% wider) than the width of the bottom element so that the surface area of the top of the connector is greater than the surface area of the bottom of the connector. A series of bores (80, 82 84) extend through the upper and lower elements for receiving pins connecting the elements together. In a preferred aspect, at least two of the bores are oriented in a non-parallel axis to one another. Typically, with respect to a notional horizontal plane passing through the centre of the assembled connector, the bores will extend at an angle to that plane, typically from 30 to 600 to that plane. Having the pins extending in different directions rather than the same direction, and in particular is a non-horizontal plane means that the chances of all the pins working free due to vibrations or the like are much reduced. .
