The present invention relates to an electric contact arrangement (1) comprising: a housing (2) having a recess (3) that penetrates the housing (2) in an axial direction (7); a sleeve (4) which is inserted into the recess (3) and which has an axial sealing surface (8) inside the housing (2) and two projections (10) outside the housing (2) which run perpendicularly to the axial direction (7); a contact pin (5) which is fixed in the sleeve (4) and which extends through the sleeve (4); an attachment element (6) which is designed to lie on the housing (2) and to be slid under the projections (10); and wedge shaped surfaces (13) between the sleeve (4) and the attachment element (6) and/or between the housing (2) and the attachment element (6) such that the sealing surface (8) can be drawn against the housing (2) from the inside by means of sliding the attachment element (6) under the projections (10).
