L'Hotellier Locking Sleeve
General Description
L'Hotellier Locking Sleeve - The use of a safety pin can be waived if the L`Hotellier ball and socket connector is already equipped with an approved locking system (e.g. Uerlings type sleeve, LS locking sleeve, Schempp-Hirth spring or Wedekind locking system) or if such a system is to be installed. LBA approved locking systems: see attachment section II. Uerlings type sleeves (specification number SE-00I/78) as well as LS locking sleeves can only be used for straight joints and transmissions, but cannot be used for 90° joints.
Installation information:
The sleeves have to be slid axially onto the L`Hotellier ball and socket connector, they may by no means be clipped radially onto the L`Hotellier ball and socket connector. Radial clipping (excessive opening of the sleeve) may lead to cracks or ruptures due to overstressing so that the sleeve cannot function properly any more.
Annual inspection of sleeves :
The sleeves shall be inspected at least once a year for the absence of cracks and sufficient locking force (selflocking ability). In the original specification for the Uerlings sleeves a biannual replacement interval is assumed. Deviations from this provision are stated in the technical information by the manufacturers
