Abstract

An injector for medical uses comprises a housing (30) on which a first holder (65) for holding the front end of a syringe (13) is movably mounted. A slide (32) is movable relative to the housing (30). A second holder (66) for attachment of the syringe piston (14) is mounted to the slide (32). When the force exerted by the syringe cylinder (12) on the first holder (65) reaches an overload condition, the first holder (65) moves counter to the action of a spring (58). An actuating element (62) connected to first holder (65) then actuates a switch (48) whereby the motor drive of the slide (32) is turned off.
