Embodiments of the present disclosure are directed to apparatuses, devices, and methods for connecting a device to an endoscope. In one implementation, an apparatus for connecting a device to an endoscope includes a multi-tined connector and a locking sleeve. The multi-tined connector is configured to engage with a port of an endoscope having a non-circular flange. The multi-tined connector includes a body portion and a plurality of tines connected to the body portion. The body portion has a lumen axially extending therethrough and an outer locking interface. The tines are radially deflectable, have outer tapered surfaces, and operate between an engaged position and a disengaged position, wherein in the engaged position, the tines engage with the port. The locking sleeve operates between a locked position and an unlocked position. In the locked position, the locking sleeve holds the tines in the engaged position, and in the unlocked position, the locking sleeve leaves the tines in the disengaged position.
