The invention concerns a vibration-decoupling device for a hydraulic circuit and in particular concerns a vibration-decoupling device for a hydraulic circuit used in an agricultural vehicle. The device has a fluid transfer element (3) able to be connected at one end (4) to a high pressure outlet of a hydraulic pump (1) and to transport fluid expelled from the pump. The another end (5) of the fluid transfer element (3) is moveably connected with a fixed element (11) such as a gear assembly housing so that the fluid can be passed to a hydraulic consumer. A support element (9) is moveably connected with the fixed element (11) and the fluid transfer element (3) and acts so that a force is exerted on the fluid transfer element (3) in one direction while the other end (5) of the fluid transfer element (3) and the fixed element (11) remain securely connected together.
