Body-monitoring system with separable link

A body analyte monitoring system intended to be attached to a limb of a living being, comprising:

• a first module, comprising attachment and tightening means configured to hold and tighten the system on a limb,
• a second module, comprising microneedles configured to be inserted into the skin to sample and/or analyze a body fluid from the wearer of the body monitoring system when the latter is positioned on the limb,
• the two modules being able to be in coupled position where they are coupled together by shape complementarity,
• wherein the first module and the second module are interconnected by a separable link, the separable link being configured to be released when a tearing threshold is exceeded, the separable link being also reusable, the threshold of tearing of the separable link being lower than the threshold of tearing of the microneedles from the skin, so that once worn, a tearing force disengages the separable link to prevent the tearing of the microneedles from the skin.
