Yes, although I found it easier to identify via the other photo of it they published. It isnt just an Aspire K1 (or clone) in the photo - a small section of the battery portion of the ecig remains screwed onto the bottom of the K1 tank, although not much.
"The possible detonator, which British law enforcement officials said was carried in the bomber’s left hand, is also unusual for a manual detonator in a suicide device, in that it appears to have contained a small circuit board soldered inside one end.
It is not clear from the law enforcement images if the object was a simple plunger switch, or included a timer or a receiver that could be operated remotely via radio signal – or some combination, or something else.
Such redundancy, if the object was the detonator, could give the bomber or a cell more than one option for deploying the device, and suggest that the bomb was not as simple in design as many terrorist devices, which often are crude and prone to failure or haphazard effect.
One independent analyst of improvised explosive devices, Michael C.L. Johnson, suggested that the object might be an electronic cigarette and unrelated to the bomb’s detonation – an understandable case of investigators focusing on a crime-scene detail early in a case.
Western bomb disposal technicians who reviewed the images for The New York Times said that a more thorough analysis of the device is difficult without more information, and that assessments of the bomb could change as the authorities analyze it further and if they collect more evidence. But its apparent overdesign, including the more powerful than usual battery, could flow from a bomb-maker’s difficulty in building a reliable detonator."
