<p>A floatable device, such as a fisherman's float tube, includes a buoyant body (2), a seat (6) adjacent an opening (4) through which a user's legs may pass and a strap (16) to extend between the user's legs. The strap has a releasable connector including a first coupling member (20) and a second coupling member (22), each with apertures therein into which the shaft of a weighted pin (24) may be inserted. The pin (24) is so weighted that it is held in place when the device floats upright by gravity alone and automatically falls out when the device is inverted, again by gravity alone, to release the connector.</p> |
