An implement coupling device (1) on a working machine (2) comprises a coupling means (11) provided with a first shaft (21); an engagement means (12) provided with a second shaft (22) arranged parallel to the first shaft (21); at least one linkage (13, 14) comprising a first portion (23, 24) connected to the first shaft (21) and second portion (25, 26) connected to the second shaft (22), which first and second portions are connected by a pivot joint (27); and a wedge (28) means arranged to be removably mounted between the first and second portions (23, 24; 25, 26), wherein the coupling means (11) and the engagement means (12) are displaceable relative to each other in a direction at right angles to the first and second shafts (21, 22) to attach or release the implement. At least one portion (23, 24; 25, 26) making up a linkage (13, 14) is detachably fixed to its respective shaft (21, 22) by a locking means (31, 32, 33, 34) in a longitudinal recess (41, 42, 43, 44) at right angles to the shaft (21, 22) and engaging with a tangential recess (51, 51′, 51″) in the outer surface of the shaft (21, 22).
