The invention relates to a hydraulic valve (8), in particular, a hydraulic valve for switching an adjusting piston (31, 32) in a connecting rod (1) for an internal combustion engine with variable compression. The hydraulic valve (8) comprises a valve housing (44) which has a first working port (A1) and a second working port (A2), as well as a supply port (P) to which a hydraulic pressure of a hydraulic fluid can be applied, 44) is displaceable against the force of a preloaded spring (10). The working connections (A1, A2) and the supply connection (P) can be sealed relative to one another and against the atmosphere by means of sealing elements (48, 49, 51, 52) when the fitting is installed in a valve receiving bore (50) of the connecting rod (1). In this case, the sealing elements (48, 49, 51, 52) can be applied sealingly to a wall (78) of the valve receiving bore (50) by the hydraulic pressure. The invention also relates to a connecting rod (1) with such a hydraulic valve (8). According to the invention, the hydraulic valve (8) is provided mechanically decoupled from the connecting rod (1).
