provides the additional advantage of securing the mounting screw 12 from view and may be secured in position for example using an adhesive in a preferred embodiment the end plate 16 is substantially circular shape to correspond to the circular shape of the weight assembly 8 as shown in fig5 in an alternative embodiment the end plate may be a shape other than circular where a non circular end plate is provided the shape of the end plate may prevent rotation without the requirement for a projection in an alternative embodiment the end plate is provided with spigots extending from the lower surface of the plate the spigots may be formed from the outer skin during the moulding process the recess of the weight assembly is provided with apertures corresponding in size and radial position to the spigots of the end plate when the end plate is inserted into the recess the spigots are received by the corresponding apertures of the recess thereby preventing relative rotational and lateral movement between the end plate and the weight assembly conversely the recess of the weight assembly may be provided with mould formed spigots with corresponding apertures being formed in the lower surface of the end plate it will be appreciated that in further embodiments various modifications to the specific arrangements described above and shown in the drawings may be made for example it is evident that the construction for securing the weights on the bar is not limited to applications in dumbbells or barbells but can also be applied to secure weights in other exercise equipment applications furthermore whilst it is described that the end plate comprises at least one projection and the recess comprises at least one receiving section this arrangement may be reversed with the recess comprising at least.
