Abstract: The invention relates to a piece that can be used for the identification, marking or decoration of objects, in particular for any type of clothing, as well as for the purpose of pairing some of these objects. The piece contains two parts sharing a common hinge, which parts are attached to one another by means of a clasp, such that the connection is preferably difficult to open once assembled. The clasp or attachment comprises a male part and a female part with a tolerance therebetween such that the piece remains clamped wherever it is to be positioned. The piece comprises rounded forms, with the minimum number of sharp edges possible, so as not to cause any discomfort once secured. The element of the piece that remains on the outside once secured can be of greater thickness and can be provided externally with suitable securing means for attaching accessories used for decoration or identification purposes, as well as screen-printed, etched or embossed patterns.
