Abstract
A connecting device usable with hydraulic or pneumatic multi-line hoses in mineral mining has a block containing bores interconnecting bore-outlets formed on end faces of the lock extending perpendicularly to one another. The bore outlets are disposed on common pitch circles on the end faces at equal spacings. Detachable fittings mate with the end faces. One of these fittings holds plug-pins in identical sockets formed by the bore-outlets. The other of the fittings is coupled with a multi-line hose with similar plug-pins which locate in sockets formed by the fitting in correspondence with the associated bore outlets. Provision is made for one of the plug-pins of each group to serve as alignment means for the other components and the plug-pin of the one fitting and corresponding socket of the other fitting can be re-orientated around the pitch circles of the end faces at will.
