Abstract: A car coupler includes first and second complementary coupling members which are respectively attached to cars by means of drop pins about which the coupling members can rotate horizontally. The first coupling member (female) includes an elongated coupling bar which is supported by a frame allowing 360.degree. of access thereabout. The second coupling member (male) comprises a frame having a latching lever and a locking lever with axes approximately parallel to the coupling bar. The latching lever forms a latching hook having a nose portion which pivots behind the coupling bar when the latching lever is pivoted to a coupling position. The nose portion defines a notch which is engaged by a locking hook of the locking lever on the other side of the bar for locking the latching lever behind the bar.
