These were used heavily in the 90s with their underwater line and I think some of the digger line.

They were also the key naming item in the M-Tron space sets.

<p>I suspect it might be related to a train coupler but I could be totally wrong. I couldn't find it in the train parts category on Bricklink. It seems similar to <a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=2920&amp;name=Train%20Coupling&amp;category=%5BTrain%5D#T=C&amp;C=11" rel="noreferrer">part 2920</a>.</p>
<p>It has an open stud on the top and an antistud on the bottom, and a regular axle hole going across. The clip things that are on one side are smaller than the diameter of a regular bar.</p>
<p>It says &quot;(C) Lego Group&quot; and &quot;3&quot; and &quot;01&quot; but I do not see a part number.</p>

I suspect it might be related to a train coupler but I could be totally wrong. I couldn't find it in the train parts category on Bricklink. It seems similar to [part 2920](https://www.bricklink.com/v2/catalog/catalogitem.page?P=2920&name=Train%20Coupling&category=%5BTrain%5D#T=C&C=11).

It has an open stud on the top and an antistud on the bottom, and a regular axle hole going across. The clip things that are on one side are smaller than the diameter of a regular bar.

It says "(C) Lego Group" and "3" and "01" but I do not see a part number.
