PCT No. PCT/DK96/00388 Sec. 371 Date May 11, 1998 Sec. 102(e) Date May 11, 1998 PCT Filed Sep. 13, 1996 PCT Pub. No. WO97/10035 PCT Pub. Date Mar. 20, 1997The element to be protected hereby is an element consisting of a pull string (2), chain, wire or the like having at each end a coupling device (3) which may be coupled onto a coupling stud (6). The element is characterised in that the string (2), the chain, etc., is mounted so high on the coupling device (3) that a momentum influences the coupling device (3) that twists the coupling device (3) off the coupling stud (6) despite the frictional force therebetween when the element is pulled.
