CA 2530819

Telescoped excavating support (16) and wear (12) members are releasably retained in their telescoped relationship by a connector pin assembly (10) removably received in aligned connector openings (18, 20) in the members (12, 16). A body portion (22) of the pin assembly blocks removal of the wear member from the support member, and a lock member (26) portion of the assembly is rotatable relative to the body, toward and away from a locking orientation, to releasably lock the body within the connector openings. A resilient detent member (28) carried by the lock member sliclingly and cleformably engages a polygonally shaped interior side surface section (24b) of a body passage (24a) that rotatably receives the lock member, the detent member yieldingly resisting rotational movement of the lock member away from its locking orientation.

Des éléments de support (16) et d'usure (12) télescopiques pour terrassement sont retenus de manière libérable en relation télescopique par un ensemble broche de connexion (10) reçu amovible dans des ouvertures de connexion alignées (18, 20) ménagées dans lesdits éléments (12, 16). Une partie corps (22) de l'ensemble broche empêche le retrait de l'élément d'usure de l'élément de support, et une partie élément de blocage (26) de l'ensemble est rotative par rapport au corps, dans une orientation de blocage et une orientation opposée à cette dernière, afin de bloquer de manière libérable le corps à l'intérieur des ouvertures de connexion. Un élément de détente élastique (28) porté par l'élément de blocage vient en prise coulissante et déformable avec une section de surface latérale interne polygonale (24b) d'un passage (24a) du corps qui reçoit rotatif l'élément de blocage, l'élément de détente résistant de manière coulissante au mouvement de rotation de l'élément de blocage dans le sens opposé à son orientation de blocage.
