1. A scaffolding comprising:
a system of upright elements and ledger elements, wherein the ledger elements extend in a transverse direction between successive upright elements, wherein the ledger elements are provided at opposite outer ends with a first coupling member, wherein the upright elements are provided with second coupling members that are complementary to the first coupling member, wherein the first coupling member of at least one ledger cooperates with the second coupling member on successive upright elements, thereby establishing first connections at the opposite outer ends between the ledger element and the pair of successive upright elements, wherein the ledger elements are provided at a distal end of the opposite outer ends with a detachable coupling device comprising a base part which is connected detachably to a body portion of the ledger element and comprising a coupling part with a coupling member extending from the base part and configured to engage one of the successive upright elements thereby establishing a second connection therewith.
