The invention relates to a flexible connection element, in particular a scales compensator (1), for connecting a first device with a second device and for passing through a bulk material from the first device into the second device, wherein the connection element (1) comprises: a base body (2) defining a conveyance channel, the base body (2) having a first end portion (3) at which an inlet opening (30) is formed and which, in case of intended use of the flexible connection element (1), is attached to the first device such that the bulk material can enter the conveyance channel through the inlet opening (30), and a second end portion (4) at which an outlet opening (40) is formed and which, in case of intended use of the flexible connection element (1), is attached to the second device such that the bulk material can exit the conveyance channel through the outlet opening (40) into the second device, wherein at least the first and/or the second end portion (3, 4) of the base body (2) is made of a flexible material and defines a flange (33, 43) which extends outwards in a radial direction and in which a respective reception space (31, 41) is defined which encircles the corresponding opening and in which a dimensionally stable stabilization element (32, 42) is inserted such that, in case of intended attaching of the corresponding end portion, a clamping force generated by a fastening element acts on the stabilization element.
