1. A fastening device for sports equipment comprising:
a first weight plate having a first outer edge, a first face, and a first fastening mechanism provided on the first face, wherein the first fastening mechanism includes an annular groove formed in the first face, the annular groove having a radial first inner wall and a radial first outer wall depending inwardly from and axially aligned with the first face of the first weight plate,
a first plurality of circular cavities located along the first annular groove, wherein each of the plurality of circular cavities has a first diameter and is formed by a radial inward extension of the first inner wall and a radial outward extension of the first outer wall of the annular groove, wherein the first plurality of circular cavities are substantially evenly-spaced around the annular groove,
a plurality of curved guides formed by radial recesses within the first inner wall and the first outer wall of the annular groove, each of the plurality of curved guides starting at a one of the first plurality of circular cavities and extending an equal length along the annular groove in a first direction, wherein each of the plurality of curved guides has a width substantially equal to the first diameter of the first plurality of circular cavities,
a notch formed by walls extending radially from the first outer edge of the first weight plate to the annular groove and located at a circumferential notch position,
a second weight plate having a second outer edge, a second face and a second fastening mechanism provided on the second face, wherein the second fastening mechanism includes an annular ridge formed by a radial second inner wall and a radial second outer wall depending outwardly from, and axially aligned with, the second face of the second weight plate,
a second plurality of circular cavities formed by a radial inward extension of the second inner wall and a radial outward extension of the second outer wall of the annular ridge, wherein each of the second plurality of circular cavities is located at a plurality of substantially evenly-spaced locations around the annular ridge,
a plurality of rollers each located within one of the second plurality of circular cavities, and
a flexible clip located in a recess provided in the second weight plate at a circumferential clip position offset from the circumferential notch position by the equal length, the clip having a first portion received and attached within a first recess part in the second face of the second weight plate extending radially from the second outer edge of the second weight plate through the annular ridge and having a protrusion extending radially from the second outer edge of the second weight plate towards the annular ridge and a second portion received within a second recess part extending axially from the second outer edge and across a side wall of the second weight plate, wherein the second portion can be flexed to axially retract the protrusion.
