A flexible tether arrangement is provided between a fluid container (10) and a cap (12) to permit free swiveling of the cap for enabling it to be screwed onto the container. A tether line (14) has one end (30) attached to the container and the other end (32') attached in a swivelable manner to the cap. The cap has a projecting boss (20) with a relatively small journal hole (28) drilled into its end and a relatively large assembly hole (26) drilled into its side so as to communicate with the assembly hole. The end of the tether line has a stop (32') thereon, made of a ball of fusion, which is positioned at the junction of the two holes. The stop is smaller than the assembly hole so that after it is formed on the free end of the tether when it projects out from the assembly hole, it can be pulled back into the assembly hole. The stop is larger than the journal hole so that after it is so pulled back, it can not be pulled out of the journal hole. The arrangement can be used to join various other associated parts.
