A wearable device comprising

• a flexible member attachable on a limb of a subject, the flexible member having a first portion comprising a first set of conducting channels, and a second portion comprising a second set of conducting channels;
• an electronic circuit coupled to the first portion and the second portion;
• a connector adapted to connect the first portion to the second portion, wherein upon connection at least one channel from the first set is connected to a channel from the second set to obtain a channel connection;
• wherein the first portion has a first set of mechanical connection holes, and the second portion has a second set of mechanical connection holes;
• wherein each conducting channel has a first end provided at an edge of a mechanical connection hole and a second end provided at a terminal connectable to the electronic circuit;
• wherein the connector comprises more than two projecting members, each projecting member being designed to engage with a mechanical connection hole;
• and wherein
• the wearable device further comprising a controller adapted to compare a channel connection identity with a predetermined channel connection and to generate an alarm signal upon identifying that the channel connection identity is different from the predetermined channel connection.
