Abstract: The connector comprises a carrier (1) adapted for fitment to a machine and a holder (130) adapted for fitment to a tool or an attachment. The carrier comprises two elongate hollow members (2), each of which contains a slide (11) situated displaceably therein, a chamber (4), which is situated between the hollow members, and displacement structure (15, 27), for displacement of the slides. The connector has connection structure for the interconnection and disconnection of the carrier and holder. The connection structure includes at least one first connection member (131) on the holder engageable with at least one first connection element (120; 113A) on the carrier, and at least one second connection member (133) on the holder engageable with at least one second connection element (113) attached to the slides.

Abstract: The machine comprises a vibrator (26) for applying vibratory forces, and a member (30) for applying non-vibratory forces to a vibratory tool carrier (52) to which is removably attached a working tool, e.g. a bucket (14). The vibrator includes an eccentric (50) and is driven by a drive (36-38). The tool carrier incorporates a first mounting (at 50) for its connection to the vibrator and a second mounting (34) for its connection to the member. The second mounting enables reciprocation of the tool carrier at the point of its attachment to the second mounting when the vibrator is in operation. The first and second mountings are spaced from each other in the direction of the reciprocation.
