1. A single-pocket cage segment of a multipart rolling-element bearing cage, the cage segment comprising:
first and second side walls connected by first and second end walls, the first side wall meeting the first end wall at a first joint and meeting the second end wall at a second joint and the second side wall meeting the first end wall at a third joint and meeting the second end wall at a fourth joint, and
a connecting element connecting the first side wall to the first end wall,
wherein the single pocket is bounded by a first surface of the first side wall and a first surface of the second side wall and a first surface of the first end wall and a first surface of the second end wall,
wherein each of the first and second side walls and each of the first and second end walls includes a longitudinally extending channel having a longitudinally extending opening and a cross-sectional shape, and
wherein the connecting element includes a first body portion connected to a second body portion, the first body portion being slidably received in the channel of the first side wall and the second body portion being slidably received in the channel of the first end wall.
 
13. A single-pocket cage segment of a multipart rolling-element bearing cage, the cage segment comprising:
first and second side walls connected by first and second end walls, the first side wall meeting the first end wall at a first joint and meeting the second end wall at a second joint and the second side wall meeting the first end wall at a third joint and meeting the second end wall at a fourth joint,
wherein the single pocket is bounded by a first surface of the first side wall and a first surface of the second side wall and a first surface of the first end wall and a first surface of the second end wall,
wherein the first side wall has a second surface parallel to the first surface of the first side wall and the second side wall has a second surface parallel to the first surface of the second side wall,
wherein the first and second surfaces of the first side wall are planar,
wherein the first surface and/or the second surface of the first side wall includes a longitudinally extending channel having a cross-sectional shape and a longitudinally extending opening,
wherein at least one retaining element is mounted to the first and/or second surface of the first side wall, the at least one retaining element having a rib or projection having a shape complementary to the cross-sectional shape of the channel slidably mounted in the channel, and
wherein a surface of the at least one retaining element facing away from the first side wall is concave.
