Patent ID: 8192105

Claim:
A set of components able to be coupled together, including: a first component having one or more stub portions extending from the first component, the one or more stub portions being formed with at least one set of radially extending teeth separated circumferentially by troughs; and a second component having a socket portion shaped to receive one of the stub portions, wherein peripherally spaced formations are provided on an interior surface of the socket portion; wherein the stub portion is able to be received within the socket of the second component by aligning the teeth of the stub portion between the formations of the socket in an unlocked position, and wherein the stub portion and socket are thereafter connected by relatively rotating the first or second components such that the teeth of the stub portion engage the formations of the socket to couple the first and second components together in a locked position and a locating device rotatably provided on each stub portion outwardly of the radially extending teeth and troughs of the stub portion, the locating device is received within the second component ahead of said radially extending teeth and troughs and rotated with the second component allowing said peripherally spaced formations to pass the locating device, and thereby assists in locating each of the stub portions within a respective second component in the unlocked position, wherein the locating device is axially spring-loaded and the locating device and respective stub portion have complementary sets of locating teeth such that, upon passing of the spaced formations beyond the locating device, the locating device is biased against the spring and the complementary sets of locating teeth engage to limit rotation of the locating device and thereby the second component with respect to the stub portion between the locked and unlocked positions.
