A pressure distribution element holding a chest strap ring for a chest harness for a mammal and attachable to a horizontal chest strap of the chest harness which is closed and opened by a hook-and-loop fastener (3, 4), by connecting a chest strap loop section and a chest strap hook section, said pressure distribution element holding said ring comprising: a chest strap connecting portion, a vertical connecting element suitable for connecting the horizontal chest strap of the chest harness to a belly strap of the chest harness, in order to form a loop around said belly strap by folding back on itself, said vertical component element including at least a loop section, continued in a lower loop portion suitable for resting on said belly strap of the chest harness, and followed by a hook section, wherein said pressure distribution element holding said ring is attachable to the horizontal chest strap of the chest harness in a releasable manner, furthermore said chest strap connecting portion includes two hook-and-loop fastener components (6a, 6b) fixed together back to back, a connecting portion hook component and a connecting portion loop component, with the chest strap ring attached there between, wherein a ring attachment portion of said chest strap connecting portion, at least on the side towards said connecting portion hook component which is opposite to the chest of the mammal during use, on the back of said connecting portion hook component, is covered by a reinforcing insert, of a width equal to or greater than the width thereof, the connecting portion hook component is separated from the chest strap ring by said reinforcing insert, furthermore at said ring attachment portion, from both sides thereof, said chest strap ring is fixed together with said reinforcing insert by fixing sewing (1 1a), limiting the horizontal displacement of said chest strap ring, the reinforcing insert prevents the connecting portion hook component from being torn out even in the case of higher loads and furthermore said reinforcing insert included in said chest strap connecting portion is fixed together with said vertical connecting element by safety sewing, furthermore the horizontal line of said chest strap connecting portion is at a right angle to the vertical line of said vertical connecting element, and furthermore said connecting portion hook component is designed to be attachable to said chest strap loop section of the horizontal chest strap of the chest harness, while said connecting portion loop component to said chest strap hook section in such a way that said chest strap connecting portion is covered at least partially by said chest strap hook section on the side towards the chest of the mammal. a chest strap connecting
