1. A device for attaching an object to an attachment rail or a seat rail in an aircraft or spacecraft, the device comprising:
a base part comprising a support surface configured to be placed onto an outer surface of the attachment rail;
at least one locking element comprising a portion having a substantially cylindrical outer shape, wherein:
the at least one locking element is configured to be received in and extend through an opening in the base part;
the at least one locking element is configured to partially protrude from the support surface of the base part along a line of protrusion;
wherein an end section of the at least one locking element has a tip portion shaped in a dovetail-type manner;
wherein the end section of the at least one locking element is formed with a shape that is flattened with respect to the portion having the substantially cylindrical outer shape; and
wherein the end section of the at least one locking element is entirely laterally contained within an imaginary extension, in a direction of a longitudinal axis of the at least one locking element, of the substantially cylindrical outer shape; and
at least one tensioning arrangement;
wherein the base part and the at least one locking element are, or are configured to be, coupled such that the at least one locking element is movable relative to the base part along the line of protrusion and is rotatable with respect to the base part; and
wherein the at least one tensioning arrangement is configured, when the support surface of the base part rests on the outer surface of the attachment rail and when the tip portion is in an engaging position relative to the attachment rail, for tensioning the at least one locking element with respect to the attachment rail.
