a body comprising an aperture;
a sleeve positioned at least partially around, and moveable relative to, at least a portion of the body, the sleeve being moveable between an open position in which at least a portion of the aperture is at least partially unoccluded so as to permit coupling of the device to an attachment receivable within the aperture, and a closed position in which at least the portion of the aperture is at least partially occluded so as to resist decoupling of the device by removal of the attachment from the aperture;
the device defining a track configured to guide the attachment receivable within the aperture along a movement path, wherein the track comprises at least a first region, at least partially defined by the sleeve in the closed position, configured to receive the attachment receivable within the aperture, wherein the track further comprises at least a second region configured to receive the attachment receivable within the aperture, wherein the track comprises at least one step or protrusion between the first region and the second region, and wherein at least a portion of a transition portion between the first region and the second region comprises at least one inclined portion.
