Device for applying compression force around the uterine cervix in different conditions in obstetrics and gynaecology, for example, as a tourniquet to stop a haemorrhage, consisting of a long hollow component (102) that has a proximal end (106) and a distal end (108), and a flexible component (110) that has a length greater than the length of the hollow component (102) and that is inserted by its ends (112, 114) in the hollow of the hollow component (102) forming a loop (120) of a variable diameter that emerges through the distal end (108), apt for wrapping around the uterine cervix and applying compression on it when at least one of the ends (114) of the flexible component (110) is pulled from the proximal end (106) of the hollow component (102).
