<p>An inflatable balloon assembly comprises a balloon having a balloon inlet (1) and an inflatable portion (8), an inflating tube (3, 4) and a compressing device which has a small hole (5) through which the balloon inlet (1) is forcibly drawn thus forming a compressed area (11) in the balloon inlet (1). The inflating tube (3, 4) incorporates a larger external diameter part (3) which remains outside the compressed area (11) and which is adapted to be connected to a pump and, adjoining the larger external diameter part (3), a substantially smaller external diameter part (4) the free end of which is forcibly drawn through the inside of the balloon inlet (1) within the compressed area (11) into the inflatable portion (8) of the balloon.</p> |
