Here's the snorkel (spelling: "Bello-Flex") in the Swimaster Skin Diving Equipment catalogue of 1962:
Its historical significance lies in it being the first snorkel to feature a flexible corrugated rubber hose ending in a mouthpiece that dropped out of the way when it was not in use, a feature popular with scuba divers who found that a regular snorkel's hard bend could catch on underwater obstacles or get in the way of the scuba mouthpiece.
The Bello-Flex also appeared earlier in the 1960 edition of the Divemaster Skin and Lung Diving Equipment catalogue, where it was described thus: "Swimaster Bello-Flex Snorkel. Designed for ultimate comfort with super-size, swivel action hose at "J"-bend, yellow rubber straight tube and comfortable mouthpiece. $2.95."
Here's Dick Bonin, the co-founder of Scubapro, explaining how he invented the Bello-Flex snorkel: "We brought out the first flexible snorkel. In Chicago, they used to sell surplus aircraft parts so I took a hose and put it on a snorkel tube, and I never forgot that. Swimaster priced it at $2.95 and everyone said we were out of our minds, but we sold them like crazy." Read the interview in full at

Swimaster was eventually sold to the Voit Rubber Company. In the early 1960s, both Voit (F5 Deluxe) and Scubapro (Hydroflex) included an improved non-collapsible version of the flexible-hose snorkel in their catalogues.
There's an International Legends of Diving biography entitled
Dick Bonin: Founder of ScubaPro - History of SCUBA Diving, stating how "he (...) introduced the first flexible snorkel and other innovations." Those innovations included the first American spearguns and the first silicone-skirted diving mask, initially marketed as "hypo-allergenic" alternative eyewear then popularised by Jacqueline Bisset in the motion picture "The Deep" (1977), where she wore a translucent version to supply more light to her face.
