A tool coupling (5) consists of a first part (51) belonging to a tool holder, and a second part (52) belonging to a tool, said parts being adapted to be easily made to co-operatively connect to each other, and easily be disconnected from each other. There are means (11) adapted to bring the parts (51, 52) in one interlocked position and in one unlocked position. The first part (51) is provided with at least one projection (10) and the second part is provided with at least one recess (10a). When the projection (10) and the hole (10a) are in a fully co-operative position where the parts are in a position suitable for interlocking, said means can be activated. Said first part (51) is provided with at least two projections (10, 11) extending in opposite directions. Said second part (52) is provided with at least two oppositely located holes (11a, 12a). each related to an end wall of said second part (52). At least one projection (11) is adapted to be said means for in a first position of the projection (11) interlocking the parts (51, 52) for rigid co-operation with each other and in a second position of the projection (11) unlock and disconnect the parts (51, 52) so that they can be separated.
