  • a two-wheeler can be secured against unauthorized driving away by a portable padlock, in that the loop formed by the bracket is guided through the spokes of one of the running wheels in such a way that movement of the latter is limited.
  • Portable U-locks can also be used to securely lock doors, for example by passing the shackle through the eyelet of a hasp.
  • a padlock Due to the possibility of carrying and moving such a padlock, it can be used flexibly at different locations and depending on the respective circumstances to secure different objects. For example, a user can choose in which way or on which section he connects the bracket to a bicycle or other object in order to secure it.
  • the design of a portable padlock with an alarm device also makes it possible to detect attempts to break in and to draw the attention of a user or other people in the vicinity of the lock to this by means of an acoustically perceptible signal.
