The sheath tapers from one end to the other, the wider end having a resealable opening (2) closed by a screw-threaded stopper (3). Projecting from the inner end of stopper (3) is an eye loop (4) connected to a hook (5) which swivels on wire loop (6) secured to tab (7). The tapered end of sheath (1) has a soft flexible undulating wall (8) and a bulbous portion (9) from which extends an annular membrane (10), the peripheral edge of which has a reinforced elastic rib (11). When assembled with the hook (5) connected to wire loop (6) a fluid chamber (12) is formed and filled with warm water (13) forming a chamber (14). Aperture (15) is formed in wall (8) to connect with bulbous portion (9) for the passage of the water (13).
