Respectfully, the OP's plant is most certainly a form of Haworthia truncata, and while it may not be a pure example of the species, it is one which is frequently seen in the trade.
Open the original poster's image to full size and pay careful attention to the concave leaf cross-section. Then notice the 'sugary' or bumpy texture to the sharply blunt, windowed leaf tips. These are definitely not Sansevieria leaves which have been amputated.
Haworthia truncata comes in a variety of forms, and the leaf tips pictured are consistent with many common truncata. In this case, I think what's confusing the issue is the extreme etoliation of the leaves—to the point where the plant is practically unrecognizable.
Haworthia hybridizers are highly prolific, and the market is awash with their unremarkable also-rans, resulting in countless hybrid seedlings of truncata mislabeled as true H. truncata.
Below is an image of H. truncata obtained from Guy Wrinkle's Exotic Plants in the 90's. Being a selected form, it differs somewhat from the OP's plant, yet exhibits the same characteristics I mentioned at the outset. It has been grown outdoors year-round under bright high shade in a 'Haworthia-friendly' climate, sparingly fertilized, and does not exhibit any of the unnatural growth characteristics frequently seen in cultivated plants. I've collected Haworthia for over 30 years, and the OP's image depicts exactly what has happened to a couple of my own truncata when forgotten in low-light situations.
Below is an unnamed Haworthia truncata hybrid obtained from Renny's Haworthia (maughanii.com). As it matures, the window markings are becoming more prominent. It's considered to be a more desirable form than the plant posted above, yet retains the general leaf structure and fan-like growth habit of the species.
The database entry for Haworthia truncata here at garden.org is somewhat of a mess, but there are several proper examples of truncata on the Cactus Art website.
I'd guess that the plant on lower-right of that page is closest to what @Screwdriver
had, before stretching occurred.
Another reference is the 'haworthia-gasteria.blogspot' site
which presents an exhaustive catalog of species with images taken in habitat, and which also illustrates their variability. There are forms of truncata with relatively straight leaf cross-sections, and also those with leaves which are almost oval in cross-section.
