The invention concerns a distance-keeping inter-process implant with a body (1) ending in its posterior part with two opposite-situated resistance protrusions (2). In the anterior part of the body (1) there are situated at least two wings (5, 6), at least one of which is a mobile wing (6) connected with the body (1) by an articulated joint. Each wing (5, 6) is provided with at least one guide (11, 13, 14, 15) of the tensioning band (4). The articulated joint between the mobile wing (6) and the body (1) is formed by the mutually collaborating shaped surface (7) of the. wing (6) and the shaped surface (8) of the body (1) and is usefully secured by the pin (12) that constitutes the axis of rotation of the mobile wing (6). In an alternative version of the implementation of the implant, the mobile wing (6) connected with the body (1) is provided with at least one arm (16) situated with respect to the wing (6) at the angle alphaamounting to from 30° to 150°.
