Chain-closing link for a bicycle chain, comprising:
- two closing parts each comprising:
- a closing plate having a first end region, a second end region, a connecting region between the two end regions, and a long hole, the long hole comprising an insertion opening, a retaining opening and a displacement region located between the insertion opening and the retaining opening, is arranged in the first end region of the closing plate, wherein the displacement region narrows from the insertion opening in a direction of the retaining opening and forms a narrowed neck location, and
- a chain pin connected in a rotationally fixed manner to the closing plate, the chain pin having at one end a pin head with a pin neck at one end and has a pin foot at an other end,
- wherein a diameter of the insertion opening is larger than a diameter of the pin head, a diameter of the retaining opening is smaller than the diameter of the pin head and larger than a diameter of the pin neck, and the narrowed neck location is dimensioned to be smaller than the diameter of the pin neck, and
