The first module (100) and the second module (200) are connected together by a separable link (300), the separable link being configured to be released when a tearing threshold is exceeded, the link also being reusable. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The body analyte monitoring system according to claim 1, wherein the first module further comprises a casing, to which the attachment and tightening means are attached. ### Claim 3 (depends on 2) The body analyte monitoring system according to claim 2, wherein the attachment and tightening means comprise a receptacle for the casing, the casing being removably attachable in the receptacle. ### Claim 4 (depends on 2) The body analyte monitoring system according to claim 2, wherein the casing is attachable to the second module by the separable link. ### Claim 5 (depends on 1) The body analyte monitoring system according to claim 1, wherein the second module comprises a capsule, which itself comprises the microneedles, and comprises a patch attachable to the capsule, the patch having a skin-adhesive power. ### Claim 6 (depends on 5) The body analyte monitoring system according to claim 5, wherein the patch is securable to the first module by the separable link. ### Claim 7 (depends on 5) The body analyte monitoring system according to claim 5, wherein the patch is removably secured to the capsule, in order to be able to change the patch while keeping the same capsule. ### Claim 8 (depends on 1) The body analyte monitoring system according to claim 1, wherein the attachment and tightening means comprise a strap. ### Claim 9 (depends on 8) The body analyte monitoring system according to claim 8, wherein the strap is made of elastic material. ### Claim 10 (depends on 9) The body analyte monitoring according to claim 9, wherein the strap is in the form of an adjustable bracelet. ### Claim 11 (depends on 1) The body analyte monitoring system according to claim 1, wherein the separable link comprises a magnet. ### Claim 12 (depends on 1) The body analyte monitoring system according to claim 1, wherein the separable link comprises a clipping. ### Claim 13 (depends on 1) The body analyte monitoring system according to claim 1, further comprising at least one guide between the first module and the second module, the guide being configured to allow a natural return to the coupled position. ### Claim 14 (depends on 13) The body analyte monitoring system according to claim 13, wherein the at least one guide comprises a cylindrical or frustoconical shape comprised in the first module and a complementary opening in the second module, the at least one guide defining an intermediate position, in which the frustoconical shape is engaged in the complementary funnel-shaped opening. ### Claim 15 (depends on 14) The body analyte monitoring system according to claim 14, wherein the first module further comprises a casing, to which the attachment and tightening means are attached, and wherein the casing comprises a frustoconical shape and the capsule 220 comprises a flared through opening, of complementary shape. ### Claim 16 (depends on 14) The body analyte monitoring system according to claim 14, wherein the complementary opening is a funnel-shaped complementary opening. ### Claim 17 (depends on 1) The body analyte monitoring system according to claim 1, wherein the threshold of tearing of the separable link has a value between 30 and 400 g. ### Claim 18 (depends on 2) A body analyte monitoring kit comprising a body analyte monitoring system according to claim 2 and a dock configured to receive at least the casing of the first module of the body monitoring device. ### Claim 19 (depends on 18) A body analyte monitoring kit according to claim 18 wherein the dock and the monitoring system form a separable link.
