A connecting piece is proposed for a static spray mixer for mixing and spraying at least two flowable components which has a tubular mixer housing (2) having at least one mixing element (3) as well as an atomizing sleeve (4), wherein the mixer housing (2) extends in the direction of a longitudinal axis (A) up to a distal end (21) which has an outlet opening (22) for the components, and wherein the atomizing sleeve (4) has an inlet passage (41) for a pressurized atomizing medium as well as an inner surface having a plurality of grooves (5) which can form separate flow passages together with the mixer housing (2), which connecting piece has an inlet region (11) for cooperating with the distal end region (27) of the mixer housing (2) as well as an outlet region (12) for cooperating with the atomizing sleeve (4), with the inlet region (11) and the outlet region (12) including a deflection angle (a) different from zero, and wherein the outlet region (12) has at its end remote from the inlet region (11) an end section (13) whose outer contour is the same as that of the mixer housing (2) so that the end section (13) of the outlet region (12) can cooperate with the atomizing sleeve (4) in the same manner as the distal end region (27) of the mixer housing (2) can cooperate with the atomizing sleeve (4).
