Abstract
Abstract A two-part lock button consists of a male and a female button half and the male part comprises a locking bolt member which is provided with one or several locking grooves and can be inserted into an opening in the female part. The female button half comprises one pair or several pairs of retaining discs which upon insertion of the male button half into the female button half will come into engagement with the one or several locking grooves of the male part thus firmly locking together these two parts. Release of the button halves can be effected by means of a mechanical or magnetic key.
