<p>The invention relates to a chain engaging device (2) comprising a first surface (10) defining a groove (8) adapted to receive a portion of a first link (28), a second surface (14) including an area opposed to groove (8) and spaced from first surface (10) by a distance greater than the maximum gap between first link (28) and an adjacent co-planar link (24), rotation of link (26) intermediate first link (28) and adjacent co-planar link (24) when the portion of first link (28) is in groove (8) permitting movement of adjacent co-planar link (24) between a first position in which the portion of first link (28) cannot be withdrawn from groove (8) due to co-planar link (24) interfering with the area of second surface (14) and a second position in which the portion of first link (28) can be withdrawn from groove (8).</p> |
