<p>The invention relates to an integral protective work clothing item comprising releasable integrated retaining elements and a digitally-activated retaining fastener. The inventive clothing item includes a harness and a retractable mechanism for securing a user to a standard lifeline. The item also comprises additional protective elements, such as a helmet, gloves and shoes which are connected thereto by means of respective elastic bands. Each of said bands is equipped with a hole for a fastener device that can only be released using a device designed for said purpose. The digitally-activated fastener comprises an electromagnet, a mobile discoidal part and a spring element. The cover of the fastener casing is provided with a hole and a tubular formation in which a pin or rod can be inserted and guided. In the operative position, the core of the electromagnet retains the rod in place and prevents the removal thereof, such that the casing and the rod are connected to one another and can only be released using the separate releasing device.
