A moveable holder for connecting a moveable member to a stationary member includes two pivoting arms mountable between the members. The moveable member has a position abutting the stationary member and a position spaced away from the stationary member. One of the arms is spring-loaded such that the moveable member is easily urged to either the abutting position or the spaced-away position when the moveable member is located at a neutral position intermediate to the abutting position and the spaced-away position.
