Abstract: The invention comprises a pair of locking devices where each locking device consists of two separate pieces. One piece of the locking device slides inside the other which prevents them from being pulled apart. Each piece can be attached to both the panel and the garment by sewing or by bonded with an adhesive. The panel, which can also be “snapped on” a garment, appears as a permanent part of the garment, not as an add on to the garment. The locking devices are made of yieldable, flexible material which bends easily for comfort of the user, and slide together very easily. In addition, as the pieces of the locking devices can not be pulled apart, the panel of material can not separate from the garment when the user's knees and/or elbows bend. The locking devices can be made of plastic which can be covered with fabric which can be washed and dried.
