tool boxes or tool bags, such as those carried in motor vehicles, cannot be accommodated.

The invention is therefore based on the object of designing a cross key that can be dismantled, so that it can be accommodated in a special pocket while largely avoiding dead space and despite its multi-pocket design is suitable for exerting large torques on a screw «

This object is achieved according to the invention in that the individual arms are designed to be insertable into a central piece.

This center piece advantageously has at least three recesses arranged at right angles to one another in a plane for receiving the one polygonal, preferably square cross-section having ends of the arms. The assembly of the cross wrench is advantageously facilitated by the fact that the center piece provided with recesses is formed in one piece with an arm of the cross wrench.

For the form-related connection of the loose arms of the cross »

with the MltteletUck are the recesses

of the center piece delimiting side surfaces, depressions are provided, which serve as a hurry for a snapper arranged at the insertion end of the arms. insert depth of the individual in a known way a round Arms having cross-section, a shoulder abutting against the end faces of the central piece is provided on these arms.

around the cross key or one of its arms to pull it off To be able to use a hubcap, the outer end of one of the insertable arms is designed as an Eralle.

The inventive design of the cross wrench has the further advantage that this is not only for loosening four different sized, usually hexagonal nuts, but different to solve a larger number large nuts or to loosen screw bolts with a square end can be used »
