Spacer for spacing a tool from a tool stand

A spacer for spacing a tool from a tool stand, the spacer comprising a spacer body and a locking member, the spacer body having first and second opposing faces, the locking member extending from a first end thereof adjacent to the first face to a second end thereof adjacent to the second face, the locking member being able to slide relative to the spacer body along a direction from the first end to the second end, the first end and the second end each being provided with at least one locking surface, wherein the spacer is arranged such that at application of a locking force each locking surface of one of the first and second ends transmits the locking force to each locking surface of the other of the first and second ends,

• wherein the first and second ends are complementary, such that the first end of one spacer can receive or be received within the second end of another spacer by running over one another along their lengths in a lengthwise direction, and
• wherein the first and second ends each have at least one corresponding tab nose and recess along their lengths, such that as the first and second ends are run over one another along their lengths, each corresponding tab nose and recess engaging one another at a given relative position of the locking surfaces.
