ABSTRACT A bobbin on which a package of thread-form or strip-form material can be wound has at one or both ends a reflexive snap ring which is selectively dis- placeable between first and second positions with an over-centre snap action. In the first position of the snap ring the end of the thread or other material to be wound on the bobbin is held fast in a slot at the boundary of a thread-receiving channel which extends circumfer- entially around the bobbin, while in the second position of the snap ring the channel is opened for access. The snap ring may be integral with the bobbin sleeve and the bobbin made of a plastics material. The snap ring can be used on bobbins which have a circumferential flange to retain the wound package and on bobbins without such a flange, in which case the snap ring is directly engageable with the end of the package. - 1 -
