configured to securely hold the swimmer against the forces of the swimming motion and remain attached to the swimmer despite the related jostling that invariably takes place as the swimmer moves in place the swimmer attachment element 110 according to one embodiment as shown in fig1 can be a simple loop adapted to slip around a swimmer 39 s ankle it can be connected to the anchor connecting element 120 the anti entanglement element 130 or the connecting element 140 at one end of the loop as shown it is connected to the connecting element 140 it can include a method that allows the loop to increase and decrease in size an increase in size can be desirable to allow the comfortable placement of the swimmer attachment element 110 around the ankle of the swimmer the decrease in size can be desirable to prevent the swimmer attachment element 110 from slipping off the ankle of the swimmer when swimming the swimmer attachment element 110 can be designed so as to allow the swimmer to easily escape if desired by configuring the loop size to be quickly increasable thereby providing a means of escape the swimmer attachment element 110 can also be designed and.
