The invention relates to a feeder element (10) for the use during the cas ting of metals in casting molds, comprising a first end (14) for placing on a mold model (12) and a second end (16) opposite thereof for connecting to o r for carrying an upper feeder part (18). The feeder element (10) comprises a passage (20) for liquid metal, extending from the first to the second end (14, 16), wherein the feeder element (10) is designed as two or multiple par ts and comprises or is made of: (i) a tube-like element (22) forming the fir st end (14) of the feeder element (10), having a maximum wall thickness of 1 .5 mm, (ii) an adapter element (24) with an opening into which the tube-like element (22) is inserted such that it is frictionally connected with the ad apter element. The adapter element (24) comprises one or more displacement l imiters (26) for delimiting the insertion path for the tube-like element (22 ). Said displacement limiters are designed such that the outer surface (46) of the edge region of the tube-like element (22) opposite of the first end ( 14) at the maximum width of the insertion within the adapter element (24) is present free on the entire circumference or in sections of the circumferenc e.
