The invention relates to a device (1) for monitoring the respiration of a user, said device comprising: - a textile support (2) with a tubular part (21) formed by knitting a largely electrically insulating ground thread, the tubular part (21) being suitable for covering the chest of the user, - at least one respiration sensor (3, 4) formed by knitting a detection thread (17), the detection thread (17) comprising an inner core of electrically insulating material and an outer sheath surrounding the inner core, the outer sheath being formed of electrically conductive material, in which the respiration sensor (3, 4) forms a conductive band (31, 41) having a first end (311, 411) and a second end (312, 412) which are positioned at a distance from each other, the ends being suitable for connection to an appliance for measuring the electrical resistance of the conductive band (31, 41).
