The invention relates to a component (1) for regulating or modifying the effective length of a round steel chain (22). Said component has at least one cross recess consisting of a longer recess (12) and a shorter recess (6). The chain can be threaded into said cross recess. The component (1) is also provided with a pin (11) for fixing said component (1) in a particular position in relation to the chain (22). Said pin forms a blocking element and has at least one groove (14) which forms the end of the longer recess when the cross recess is free. Normally, said groove is pushed by a spring (10) into a position in which the pin (11) blocks the cross recess.
