Abstract: A device (1) for cleaning an optical waveguide end (2) comprises a guide portion (3) for receiving the optical waveguide end (2) in a stable position and a rotatably mounted spool (4) onto which a flexible cleaning element (5) is wound. The guide portion (3) and the spool (4) are positioned relative to one another such that an optical waveguide end (2) received by the guide portion (3) is able to be pressed against the wound cleaning element (5). The cleaning element (5) is able to be unwound from the spool (4) such that different portions of the cleaning element (5) are able to be applied to the optical waveguide end (2) during unwinding.

Abstract: The invention relates to a plug connection for a mobile optical multi-thread plug part (2, 3) which comprises various adaptive means. The adaptive section (PA1) of the first adaptive means (6, 8) is longer than the adaptive section (PA2) of the second adaptive means (7, 9) in relation to the longitudinal axis thereof. The adaptive means (6, 7, 8, 9) are embodied in such a manner that initially the first adaptive means (6, 8) and then the second adaptive means (7, 9), after surpassing an insertion path, can be impinged upon by associated guiding means of the plug part, when the plug part (2, 3) is inserted.
