We extend the Skyrme-Hartree-Fock (SHF) approach to study the double-Lambda hypernuclei. The nucleon-nucleon and Lambda-nucleon interactions are taken from a recent work where the SHF method was applied to a successful description of the single-Lambda hypernuclear systems. For the Lambda-Lambda force a simple Skyrme-like form has been used. We discuss the sensitivity of the calculated Lambda-Lambda binding energy and the Lambda-Lambda bond energy to the Lambda-Lambda and Lambda-nucleon force parameters. It is found that the existing Lambda-Lambda hypernuclear data do not allow the extraction of an unambiguous information about the Lambda-Lambda force.
