Abstract
A welding sleeve connector for the connection of molded components made of a thermoplastic synthetic resin employs the heat energy generated by pyrotechnical material. This connector has a thermoplastic sleeve and a plurality of pyrotechnical heating charges for producing the welding heat energy. Each charge is individually enclosed in a casing of a solid material arranged in the sleeve, and the encased heating charges are separately positioned in the sleeve at predetermined spacing from each other over the circumference of the sleeve. The connector also has a device for igniting the heating charges.
