1. A plastic cage, comprising:
first and second side rings that are axially spaced apart from one another;
a plurality of cage webs that connect the side rings to one another and between which pockets are formed for receiving rolling elements;
a first cage end having a first closure element; and
a second cage end having a second closure element that corresponds with the first closure element, such that the first and second cage ends are operable to be selectively engaged such that the first and second closure elements limit movement of the first and second cage ends relative to each other in axial, radial, and tangential directions, wherein the first closure element comprises:
a first projection that extends from a boundary surface of the first cage end; and
a first latch that extends a first radial direction from the first projection to a first free end of the first latch that is distal from the first projection; and
wherein the second closure element comprises:
a second projection that extends from a boundary surface of the second cage end; and
a second latch that extends a second radial direction opposite the first radial direction from the second projection to a second free end of the second latch that is distal from the second projection, the second free end of the second latch having an axial extension that extends axially outboard to a tangential extension that extends to one of the first and second side rings therefrom.

6. A cage for a bearing, comprising:
a first side ring and a second side ring in an axially-spaced relationship with the first side ring and connected therewith via a plurality of cage webs that define pockets for receiving roller elements therein;
a first cage end extending between the first and second side rings and having a first plurality of closure elements that protrude outward from a first boundary surface, wherein the first plurality of closure elements includes a first closure element, comprising:
a first projection molded onto the first boundary surface; and
a first latch that extends a first radial direction from the first projection to a first free end of the first latch; and
a second cage end extending between the first and second side rings and having a second plurality of closure elements that protrude outward from a second boundary surface, wherein the second plurality of closure elements includes a second closure element, comprising:
a second projection molded onto the second boundary surface; and
a second latch that extends a second radial direction opposite the first radial direction from the second projection to a second free end of the second latch, the free end of the second latch having an axial extension that extends axially outboard to a tangential extension that extends to one of the first and second side rings therefrom,
the first and second cage ends being operable between a disengaged condition, wherein the first plurality of closure elements are in a spaced relationship with the second plurality of closure elements such that a gap is defined between the first and second cage ends, and an engaged condition, wherein the first closure element is engaged with the second closure element, such that movement of the first and second cage ends in axial, radial, and peripheral directions is limited by contact between the first and second closure elements; and
wherein the first and second projections are positioned wholly axially inboard of the first and second side rings.
