A marking instrument comprises a marking tip (2) carried at the end of a tubular member (1) surrounding a channel for conducting marking fluid to the tip (2), wherein the tip has a tubular rear end section (3) joined to the tubular member so that the tip is fixed at an angle to the longitudinal axis of the tubular member, and at a connection plane where the tip and tubular member are joined, the tubular member and tubular section have complementary profiles of substantially the same shape. Preferably the complementary profiles are circular in shape at the connection plane, which precludes the necessity to rotationally orientate the components when bringing them together to be joined.
