<p>A device for releasably mounting a working implement (50) on a working arm (18a,18b), the device (10) comprising a housing (15) secured to the working arm (18a,18b), a latch member (24) linearly movable from a latched position in which the latch member (24) engages with a receiving means (53,54) of the implement (50) to retain the implement (50) relative to the device (10) and hence to the working arm (18a,18b) and an unlatched position in which the latch member (24) is disengaged from the receiving means (53,54), the latch member (24) being slidable within the housing by means of an actuating means (26,40) which operates in a direction generally parallel to a direction along which the latch member (24) moves between its latched and unlatched positions. The actuating means (26,40) comprises a piston (40) and cylinder (26) arrangement wherein the cylinder (26) is provided by a bore (26) in the latch member (24) and the piston (40) comprises a pin or rod in sealing engagement with the cylinder (26), relative movement between the piston and cylinder being achieved when fluid is introduced into the cylinder. <IMAGE></p> |
