Abstract: A wheel immobilizing cover for roller blade roller skates includes an elongated channel, a non-adjustable or fixed bridle of flexible, rubberized material which is subject to arcuate movement about an effective pivot point located on the sidewalls of the channel and an adjustable bridle coupled to the base of the channel. The adjustable bridle moves arcuately about the coupling point. The fixed bridle which is detached, at its outer end, from the base captures the front wheel of the roller blade skate wheels on the upper forward quadrant of the wheel and the adjustable bridle captures the rear wheel of the roller blade skate wheels on the upper rear quadrant of the wheel. When the front wheel rotates the wheel drags the flexible fixed bridle along the flexible, fixed bridle effectively pivoting about some pivot point on the channel and because of the difference in the paths of arcuate travel between the front wheel and the fixed bridle, the front wheel is clamped and immobilized.
