A clamp apparatus (20) for selectively occluding a tube comprises a base member (22) to which the tube is attached or through which it passes, and a slide clamp (24) that slides relative to the base member and relative to the tube. The aperture (38) in the slide clamp has a relatively open hole, through which the tube passes when the clamp is an open position, and a relatively constricted slot preventing fluid flow through the tube. A deflectable cantilevered locking arm (60) on the base interlocks with a detent (48) on the slide clamp to lock the slide clamp at the occluding position. A release tab (64) to release the locking arm from the slide clamp is located off center to avoid inadvertent activation. The deflectable arm is unstressed when the slide clamp is in either the occluding or the open positions.

L~invention concerne un appareil pinceur (20) pour boucher un tube de façon sélective, comprenant un élément de base (22) auquel le tube est attaché ou au travers duquel il passe, et une pince coulissante (24) qui coulisse par rapport à l~élément de base et par rapport au tube. Une ouverture (38) dans la pince coulissante comporte un trou relativement ouvert, à travers lequel le tube passe lorsque la pince est en position ouverte, et une fente relativement rétrécie empêchant l~écoulement de fluide à travers le tube. Un bras de verrouillage en saillie fléchissant (60) sur l~élément de base s~enclenche avec un cliquet (48) sur la pince coulissante pour verrouiller celle-ci dans la position de bouchage. Une languette de libération (64) pour libérer le bras de verrouillage de la pince coulissante est située en position décalée pour éviter son actionnement accidentel. Le bras fléchissant n~est pas sollicité lorsque la pince coulissante occupe la position de bouchage ou la position ouverte.
