A connection arrangement (1) serves for establishing a hydraulic connection to devices of internal combustion engines. A connection element (2) and a connection piece (3) are provided in this context. In order to establish the hydraulic connection, a connection face (5), having convex curvature, of the connection element (2) is loaded against an at least approximately conical bearing face (6), of the connection piece (3), which is oriented inward with respect to a longitudinal axis (8). In this context, the convexly curved connection face (5) of the connection element (2) bears, in the bearing region (7), directly against the at least approximately conical bearing face (6) of the connection piece (3). Also, the connection element (2) is harder than the connection piece (3) This results in plastic deformation of the connection piece (3) during initial assembly. Also provided is a positive longitudinal offset (12) by which an active engagement region (10) of the external thread (9) is offset from the bearing region (7) along the longitudinal axis (8). This avoids critical plastic deformation of the external thread (9).
