The hand access port 10 comprises a sleeve 12, having a proximal end 13 and a distal end 14. A flange 15 is located towards the distal end and is used to secure the device to a patient's body. Above the flange 15 is an inflatable chamber 16 having an entry opening 17 through which a surgeon's hand can enter. An insufflation valve 20 in provided on the outer sleeve of the chamber 16 so that the chamber can be inflated prior to the insertion of the surgeon's hand into the device. Beneath the flange 15 is the tensioning device 30 which comprises a pair of identical arcuate bands 32 which are engaged together through two orifices at each side of the edges of the inner sleeve 11 which protrudes into the patient's body. Each band is formed with a bend 40 formed in the middle with two male studs 42 at one end and two orifices 43 at the other end. The tensioning device 30 is formed by reversing two bands 42 so that the male studs 42 engage in the orifice 43 of the other band.
