The present invention provides an apparatus for use in a peristaltic pump 20 which prevents an inadvertent free flow condition prior to loading or after removal of an I.V. tube 26 in the peristaltic pump 20 and which also prevents the inadvertent occlusion of a loaded I.V. tube 26 in the peristaltic pump 20. A standard I.V. tube 26 has a slide clamp 109 provided thereon. The apparatus includes an I.V. tube groove 29 into which the I.V. tube 26 is positioned, a slide clamp receiving area 62 into which the slide clamp 109 is inserted, and a biased sliding member 81 which the inserted slide clamp 109 engages such that the I.V. tube 26 cannot be loaded into the apparatus without the slide clamp 109 occluding the I.V. tube 26. The present invention also contemplates a slide clamp 109, compatible with the apparatus having a surface pad 125 for facilitating automated identification of the slide clamp 109, in cooperation with a nonobstructive sensor 85 in the safety apparatus. The present invention further contemplates a slide clamp 109'. having an I.V. tube receiving aperture 110'with an inner diameter profile which minimizes friction between I.V. tube contacting surfaces 126 of the aperture 110'as an I.V. tube 26 is slid transverse to its length within the aperture 110' and which has a surface pad 125 for facilitating automated identification of the slide clamp.
