Abstract: A docking drive for a testing head comprising a plurality of locking mechanisms (10) each provided with an own locking drive (14, 21-28) comprises a synchronizing device (11, 12, 13) synchronizing the locking drives (14, 21-28) of the locking mechanisms (10). It may comprise a respective trapping device (15a, b) provided in a plurality of locking mechanisms (10) each retaining a locking element (50) to be locked in the respective locking mechanism (10) in a certain position. A locking element (50) of a docking system comprises a base (51), a locking section (55) and a connecting mechanism (52-54) provided between the base (51) and the locking section (55) and being manually releasable without tools. The locking section (55) may be resiliently supported opposite of the base (51). The locking element may comprise a first retaining section (56) for the trapping device (15) and a second retaining section (57) for a locking device (16).
