Abstract
A bone spreader includes two tubular pin holders which are connected to one another by a parallel guide system, and two pins that are configured to be connected to the bone parts that are to be spread apart. In order to give the bone parts that are to be spread apart a more secure position in relation to one another, at least one of the pin holders is provided with a locking device for a pin located in the pin holder. This locking device includes a locking finger which is movable tangentially with respect to the pin holder and which, in the locking position, engages in a transverse groove of the associated pin and can be formed by a pivotably mounted hook.
