The open space is defined in the length direction in part by a front contact surface at a forward portion of the clamp adapted to engage one end of the slider, and a rear contact surface at a rear portion of the clamp, and adapted to engage an opposite end of the slider. The spring connects the stationary frame with the front contact surface such that with deflection of the spring the front contact surface is moveable relative to the frame in a direction of a lengthwise axis of the clamp. ## Claims ### Claim 1 A clamp for removably holding a slider, the clamp comprising: a stationary frame that includes a stationary rear frame member at a rear portion of
