A removable tool assembly for a backhoe apparatus of a construction equipment machine having spaced apart parallel first and second fastening pins, said removable tool assembly comprising an attachment mechanism for releasably attaching said removable tool assembly onto the backhoe digging apparatus, the attachment mechanism comprising:

a first attachment element having first receiving areas (Ra1, Ra1′) adapted to receive the first fastening pin, and
a second attachment element having second receiving areas (Ra2, Ra2′) adapted to receive the second fastening pin,
wherein the second attachment element is movable relative to the first attachment element between a first position, in which the first and second fastening pins can be removed from the first and second receiving areas, and a second position, in which the first and/or second fastening pins are tightly retained in the first and/or second receiving areas,
wherein the first and second receiving areas are closer in said second position than in said first position;
a driving means adapted to move the second attachment element from the first position thereof to the second position thereof and vice versa;
wherein the first receiving area and the second receiving area are defined by C-shaped portions of the first attachment element and the second attachment element, said C-shaped portions defining openings through which can be inserted the first fastening pin and the second fastening pin into the first receiving area and the second receiving area, wherein the openings respectively defined by the C-shaped portions of the first and second attachment elements are oriented toward each other;
and
wherein the second attachment element comprises third receiving areas adapted to receive the first fastening pin in the second position of the second attachment element.
