A bayonet-connection-undoing device includes a projection configured for attachment to a hand so as to extend therefrom for depressing a pin to undo a bayonet connection. The device may have a finger ring to which the projection is attached, in which case the attachment to the hand can be made by wearing the ring on the hand, optionally the ring being disposed inside a hand glove, with the projection emerging from the glove. Alternatively or in addition, the device may further include sections of a pipe cleaner, the connection, and the pin which is configured for mutually fixing one of the sections to another. In this case, the depressing is down into a position at which the pin is retracted out of the connection and maintained, without need for the depressing, in a contracted state by relative movement of the sections.
